Yamaha XT400 Adventure Motorcycle Riding in NZ

1 year of inaction

2011-07-05T17:26:00.000+12:00

Well one year has gone by since my last post.
I haven't been up to any adventure riding.
I have been a bit boring really. Just working and plodding along in the global recession.
I guess I have been more focused on rebuilding my Honda NSR250R. (My other blog)
I still use the XT most weeks just for commuting.
Some of my friends have bought adventure bikes so maybe this summer I will get back into it a bit more.

60k kms reached

2010-07-04T15:32:00.000+12:00

It is the winter months and not too much has been happening with the XT400.

I have been using it for a bit of commuting and general use, nothing particularly adventurous.

I have moved from Whakamarama to Te Puke and have found a fun way to get from Te Puke to Welcome Bay over Rocky Cutting Road which incorporates a tight twisty hilly gravel road.

Today I clocked up 60,000 km on the odometer.

On Sunday night (4th July 2010) I left Wobbly's about 1am at night after watching the Catalunya MotoGP. It was dark/cold/very windy (and windy) and raining, so I took the Rocky Cutting /Reid Road track just to make things a bit more interesting.

The XT seemed to be losing power. This was quite worrying at 1:30 am on a dark wet and windy night on a single lane gravel road. However, I made it home OK. I need to adjust the headlight to point up a bit as it was difficult to see very far ahead in the dark, especially when under brakes with a visor splattered with raindrops.

Change Needles and jets

2010-04-17T09:36:00.000+12:00

OK, well I went into GP Honda in Mt. Maunganui and rummaged through their jetting containers.
I got 2x95 main jets and 2x90 main jets. ($7 each)
I also got 2x needles[needle number reqd].($5 each) These needles seemed exactly the same as the original XT CV carb needle, with just the numbering now different (and sensible).All Keihin stuff.

I put in the new needles and 90 jets.(down from 100)
Took it for a spin down the road and it all seemed very similar.

I think I really need to try advancing the ignition in the upper midrange to top end, to get it to have decent response up there.

Dusty Butt '10 SBC: Overview

2010-01-20T15:20:00.001+13:00

Well the little 125cc four stroke Honda did extremely well.

About 3700km over 6 days. And a lot of that was at full throttle, and near max revs.

The engine did not miss a beat. It used about 1.2 litres of oil over that distance (it holds 800ml) which is not too bad I suppose. I do not know if the oil is getting past the rings or whether it is exhausted out the crankcase breather into the airbox. Probably a bit of both.

Also, the suspension and drum brakes were surprisingly good. I guess by "good" I really mean "not crap". I was able to blast along over all sorts of terrain with no major complaints in the handling department at all.

I ran out of time to check over the engine before going on this ride, other than to set the tappets. I really had no idea if it was in very good condition or not. However the Honda NXR engine (XLR125 engine) is pretty tried and tested. The big "H' came through for me on this ride. I am not a Honda fan in particular, but I am very impressed with this little Honda.

The Dusty Butt route was unbelievably amazing. A really excellent trail. The NXR was pretty slow on the straights and up the hills, but was overall enjoyable enough. As soon as the route got twisty I was having a ball. The bike comes into its own on twisty downhill gravel. I caught and passed many much more powerful bikes on the downhill gravel sections. I guess the light weight really helps in that situation.

Overall the bike and the route combined to give me a much more fun experience than I was expecting. Really fun!

The other factor of course is the people. On the 1 dayer you don't really get to interact with very many others. However, the 2 dayer is great for meeting new people and making friends. Everyone is just so positive in attitude and willing to help out, no matter what the issue. It seems a shame to waste the opportunity of experiencing the 2 day environment just to do the 1 dayer. If was ever to do the 1 dayer, I think I would do the 2 dayer first, and then give myself a 2 day rest. Then I would happily have a crack at the 1 dayer.

Would I do the Dusty Butt again on a 125cc machine? Well,.. one guy rode around on a KDX125 two stroke with a max speed of about 130kph. This is much better than the NXR at about 90kph. I think that if I could get something like that KDX125 and tune it up to the max, then I could be interested. In general, I would be happy on something that can sit on 120kph on the gravel into a strong head wind. If a tricked up KDX125 could achieve this then I would definitely be interested. On a bike like that, I could imagine that you might just be in with a chance of winning the DB1k outright. Probably a very slim chance though.

Having said that, the whole idea of the Small Bore Challenge is to ride around on a gutless piece of crap. I have done that once, and am not all that keen to do it again. It is just a bit too boring on the straights and open uphills.

Tolls & Ferry: $232.00

Other: $86.20

All up: $881.56 But this is just costs incurred on the trip. It does not include setup costs or post-event costs or tyre wear etc. I need to buy a new Fr brake perch, replace a rear spoke, do some welding work on the pack frame and probably some other little things.

Tyre wear:

Rear tyre (Pirelli MT60 110/90 17): started off with 8.5mm of tread depth and ended up with 5.5mm of tread depth. The trip covered 3686km, so this gives 1229km/mm of tread wear. The Mitas E-09 on my XT400 usually gives about 650-800km/mm tread wear.

Front tyre (Pirelli MT60 90/90 19): I did not record the tread depth when new. Tread depth after 3686km is 5.0mm

Fuel works out at (3686km/$303.18 =) 12.16km/dollar

Trip works out at (3686km/$881.56 =) 4.18km/dollar (although true cost is higher)

Took inland scenic route to Oxford and then on to Lees Valley.

Chain came off mid-crossing of the Okuku river.

Other bikers on hand gave some help.

Then on to Hanmer and Jollies Pass into Molesworth/Awatere.

Rained heavy for about 20 minutes and made the ride a bit more interesting.

Dusty Butt '10 SBC: Day 4 Alexandra to Fairlie

2010-01-20T15:03:00.000+13:00

Sunday 17th January 2010

Second day of the DB1k

Set off with the Jatz's and The Boy.

The first pass was fantastic. I was blasting along and soon was well ahead of the Jatz's.

Quick stop in Cromwell and on to Thompsons Track.

Gate tag with TransAlper, but bike fell off stand and broke front brake perch.

TransAlper went on to catch up with others and I repaired brake perch with some wire. The fix lasted all the way back to Tauranga.

Didn't know about the pub at St. Bathans so continued on to Omarama. HoT and QOTH were waiting there and were very surprised to see me come in 6th on the 125cc machine.

On to Benmore where I forgot the lock code and had to throw bike over a fence.

Benmore back road was amazing.

Then out of Black Forest and along the straights to Fairlie.

Got back to the Gladstone Pub at 4:30pm. Talked with Woodman (RedKLR650) who had been there a while.

Back to camp for a shower and change of clothes.

Back to pub for a meal and spin shet/debrief.

Got to bed approx 11pm

Start Alexandra 12341km 07:50 hours

Finish Fairlie 12743km 16:40 hours

402km over 8:50 hours

Dusty Butt '10 SBC: Day 3 Fairlie to Alexandra

2010-01-20T14:55:00.000+13:00

Saturday 16th January 2010

Started off on the DB1k approx 7:10am

See forum links here and here for general discussion and pics.

Travelled with Alane (XT600), Underground 2-up with Ms Underground (Africa Twin), and Mountie (F800GS)

Coffee break at Kurow.

Alane was great and slowed up for me so I could stay on route. Top man!

As a side note, it was great to watch Alane kick start his old 600. There is just something about kicking over big singles that I love.

Had a beer with Alane at Clarks Junction pub

Had to reweld exhaust header at Laurence. Alane rode on. This involved going to the local Video hire shop (of course) and asking to get my exhaust welded. Forty five minutes and $20 later and it was done.

Met the Jatz's just out of Laurence.

Had to find my way with no proper route information but did it. Wheel marks left by previous riders helped a lot.

Gave Shrek my front tube just out of the Lake Onslow Rd before the Serpentine to fix his front flat.

Chain came off on Serpentine right next to Racing Dave's abandoned NXR125.

Pulled in to Alexandra approx 8:30pm.

Brilliant day.

Thai resaurant with Jon24 and Aslan.

Start Fairlie 11700km 07:10hours

2010-01-20T14:47:00.000+13:00

Friday 16th January 2010

Got off the ferry at 3:30 am

Rode out along the Port Underwood road for about 30 mins but was too tired.

Stopped and lay down on the side of the road to sleep for about an hour.

Rode on at 5:00am.

Exhaust header became detached just after Rarangi.

Lost 2.5 hours in Blenheim getting exhaust header welded up.

I now had to flag the idea of doing the Molesworth/Awatere section and just headed straight down along SH1

In Blenheim I also checked and topped up the oil, replaced a now missing engine mount nut and tightened up a bolt holding on the rear pack frame support.

Arrived at the Gladstone Pub in Fairlie 4:45pm. Met "XF650" and had a beer with him as others arrived. Great turnout at the Pub BBQ. Really good.

Got accommodation organised thanks to HoT. ($35 for Fri and Sun night) This saved me having to pitch my tent at the local camp ground.

Thursday 14th January 2010

I rode off at about 8am and went via Waikaremoana, Napier, Masterton to Wellington.

Initially had problems with the kick start lever always flicking out at high speed.

Also, engine seemed to be running really hot. I removed the front mud flap and it ran a lot cooler.

Dusty Butt '10 SBC: Preparation

2010-01-20T14:36:00.001+13:00

OK this does not include the XT400 but it is one hell of an enjoyable adventure ride.

The Dusty Butt 1000km is to be held in the lower South Island this year.

There is a Small Bore Challenge sub group for those that do the ride on a bike with 125cc or less.

On November 10th 2009 I bought a '04 NXR125 off TradeMe from Gisborne for $900 with the intention of riding it down to do the DB1k SBC.

I did a bit of work on the bike to get it ready:

Replaced farm knobblies with Pirelli MT60's Fr and Rr ($170 from Coastline Honda)

Got rear rack welded up to take Top Box and Pack rack ($100 Wobbly)

Bought second hand indicators and 2 new lenses.

Replaced rear shock lower bearing and regreased swingarm bearings

Closed up tappet clearance from 10/7 thou to 5/4 thou

Checked and re-greased steering head bearings

Lubed the cables and freed up the throttle

Attached front bikini fairing properly

New front sprocket and chain. Used old alloy Rear sprocket off my CR (13 tooth front, 49 tooth rear)

Installed chain guard off my XT400

Bought spare tubes for puncture repair

Swapped out the standard cardboard air filter for two dish washing sponges.

Replaced the broken gear shift shaft.

Changed oil (Motul 3100)

Added an after market Front brake perch clamp that had thread in top for rear view mirror ($28)

Added rear view mirror from wreckers

Checked front wheel bearings.

Replaced rear wheel bearings

Checked and cleaned Fr and Rr Drum brake pads

Replaced front fork fluid

I ran out of time to pull the head and barrel off to check the engine out properly, so I just hoped it would be OK. It is basically an XLR125 engine with 10k on it so should be sweet as these engines have been truly tried and tested.

Work commitments really piled up near the time of the DB1k and I actually posted in the forum saying that I wasn't going to be able to make it due to stupid workloads.

However, I managed to do a lot of trouble-free productive hours in the lead up to the DB1k and amazingly was able to depart in time to get there after all. I was a bit disorganised as a result, but at least I got there.

The NXR weighs 123kg with 2 litres of fuel on board

When fully loaded up :

Tank bag 7.5 kg

Rack pack 13 kg

Top Box 12.5 kg

it weighs 156 kg. With a full tank I guess this goes up to about 165kg.

Then I sit on it and it is 267kg rolling along the road.

At DB1k I lose the tank bag and top box resulting in a bike weight of about 136-145kg depending on fuel level.

BMC: Overview

2009-12-07T14:10:00.000+13:00

Start 53943 km

End 58392 km

Total Distance = 4449 km

The best day was from Fairlie to Invercargil. The strong wind made the high gravel passes a really fun challenge. Combined with the magnificently scenic visual impact it was a totally exhilarating day.

Otago and Southland have many roads suited to adventure riding, with amazing scenery. Hopefully I will get to travel a few more of these roads in the future.

The XT400 did not miss a beat. All I did was fill it up with gas and oil the chain. I did check the valve clearance on one valve but it was fine. I really need to clean the air filter now!

If I do another trip like this, I will sort out a better, more comfortable seat. My sore bum was the only really limiting factor that I struck during this little adventure ride.

BMC: Day 8 Wellington to Tauranga - Home.

2009-12-07T13:57:00.000+13:00

Wednesday 2nd December 2009

Departed Wellington approx 9:00am

Rode to Wanganui and went along the Whanganui River to Pipiriki. Then over to Raetihi.

After so many miles on the bike, my bum was starting to ache. Usually the ache went away when i got onto gravel roads as I have to continually shift my body weight around on the bike to maintain good steerage. However, I had got to the stage where it was really quite sore.

I did have more adventurous plans to go elsewhere, but due to my aching bum, I decided to take the main roads straight from Raetihi to Tauranga.

I stopped off in Oropi for 15 minutes to see Dave's very recent purchase, an NSR250, and then home to Whakamarama.

Had pizza for dinner.

Wet windy day although did go for a bit of a walk around central Wellington during a fine spell of weather.

BMC: Day 6 Greymouth - Karamea - Picton

2009-12-07T13:40:00.000+13:00

Monday 30th November 2009

Departed Greymouth approx 9:00am

On to Westport [rock falls] and up to Karamea and to the complete end of the road at Kohaihai where the Heaphy Track starts. Light rain most of the time but was still fun.

Talked to an Israeli tramper who had hiked back out after hiking in for one day as he had forgotten his raincoat. D'oh! He was soaked through but in reasonable spirits.

Then back to Karamea pub for a beer and a vege soup.

Then back to Westport and on to Nelson.

Went part way over the Maungatapu track only to find that it was closed. I wish they could put up a sign telling you so at the start of the Maitai River Rd.

So back into Nelson and over the Queen Charlotte Drive to Picton.

I had a green Thai curry and booked my ferry ticket. $73

Set sail at 10:30pm and arrived Wellington 1:30am.

Crashed out at Pete's at 2:00am.

BMC: Day 5 Invercargil to Greymouth

2009-12-07T13:24:00.000+13:00

Sunday 29th November 2009

Got up about 7:00am. had another pre-paid $11 breakfast.

Packed up my tent and oiled the chain.

Departed the campground approx 9:10am.

There was a toy run organised to go out to Wyndham where the street racing was to be held.

However, due to the nasty looking weather forecast I decided to make tracks back up North.

I went through Winton and on towards Frankton. Then up the Coronet Peak Rd to Skippers Rd and out to Skippers Bridge. This is a very narrow twisty gravel road with totally blind single lane corners. It would not be so bad except for the number of tourists and small buses travelling it.

On to Wanaka. Here I diverted off to Treble Cone just to have a look. Then back to Wanaka and over to Haast. I made sure I got to Haast before 5pm just in case the petrol stations were shutting early to force people to stay the night. However, upon arrival I noticed a sign that said 24 hour card operated pumps. I did not need to check this out as the petrol station was open.

Up the West Coast Rd to Hokitika. I decided I did not need to fill up at Fox Glacier, as a result I VERY NEARLY ran out of gas before Hokitika. I must have pulled into Hokitika with less than 100 ml of petrol left. I was going to stay the night in Hokitika but decided to press on to Greymouth as I was feeling quite good.

BMC: Day 4 At the Rally.

2009-12-07T13:18:00.000+13:00

Saturday 28th November 2009

I had a good sleep-in in my tent.

The wind was up and was bitterly cold. It stayed like this for the duration of my time in Invercargil. I got in the queue for my $11 pre-paid breakfast and by the time i got to the servery they had run out of bacon and beans. Watched the road racing at Teretonga and then took in some of the speedway racing over at the speedway track. Both within walking distance of the camp ground.

Spent the evening in Jonno's campervan talking to an ex British Army helicopter pilot who used to fly around Southland doing live deer capture. Very interesting converasation.

BMC: Day 3 Fairlie to Invercargil

2009-12-07T11:47:00.000+13:00

Friday 27th November 2009

Slept in till about 8:30am. Washed a few clothes. Checked the valve clearance on the noisy tappet (RH Exhaust). It seemed perfectly fine at 4 to 5 thou.

About 11:30am took off to Burke's Pass and headed along Rollesby Valley Rd then onto Mackenzie Pass Rd. Then along the Hakataramea Pass Rd. Fantastic scenery. Came out at Kurow where I gassed up.

Then on to Duntroon and over Dansey's Pass. It was blowing a gale and it was difficult going. I adapted my riding to suit the blustery conditions and really started to enjoy the ride immensly.

[more descriptive text reqd]

The Dansey's Pass Pub was an unexpected but completely welcome sight. What a great Pub! I stopped and had a beer and a couple of toasted sandwiches. Appriox 1:00pm.

I gassed up again at Ranfurly and headed off to Patearoa and through Paerau, along Upper Taieri Paerau Rd onto Linburn Runs Rd and then onto the Deep Creek Rd which leads onto the Lake Onslow Rd and through to Roxburgh. This was a pretty cool road!

Back onto the seal and through to Raes Junction, Tapanui, Gore and Invercargil.

I rode out onto Oreti Beach at 7:30pm to find that the beach racing had been cancelled due to high winds and also high-ish tide due partially also to the high winds. This was a bit of a bummer. I had just ridden for three days solid. I had really been looking forward to seeing the beach racing.

I went back to the Rally campgound near Teretonga racetrack and checked in and set up my tent. I went into the main marquee and got myself a couple of whiskeys. I started to look for Jonno, and almost instantly found him amoungst a few hundred bikers. Sweet.

Crawled into my tent at midnight. Job done!

BMC: Day 2 Picton to Fairlie

2009-12-07T11:36:00.000+13:00

Thursday 26th November 2009

On the Wellington side at the ferry terminal there were about 10 other bikes all heading down for the Burt Munroe Challenge. I got talking to them all as you do. One guy had put some Ducati 1098 mufflers on his VFR800. Looked pretty cool.

I got about 2 hours sleep on the ferry lying on the lounge bar floor with my ear plugs in.

Set off from Picton about 5:50am along the coast road to Rarangi and Blenheim. I had a major front end slide on a patch of gravel on seal just as the sun hit me with blinding sun strike at one point. Quite dangerous but I came out of it totally OK.

On towards Kaikoura and stopped to see if the Awatere Valley Rd through the Molesworth Sheep Station was open. It wasn't so I had to carry on via the Inland Kaikoura Rd stopping at Mt. Lyford.

Then along the Lewis Pass to reefton and through to Nelson's Creek and Inchbonnie. Riding along the Lewis Pass into a head wind at times I found the power of the XT lacking a bit. I was often down to 90km/h in 4th gear. To be able to ride fast enough to enjoy the more open sweepers on tarmac roads, a bit more horsepower is required. I can see why 600-660cc single cylinder 4 stroke adventure bikes are quite popular.

The Nelson Creek to Inchbonnie back road is quite open hardpack dirt/gravel and I was able to cruise at 90-100km/h quite safely. It was a bit of higher speed non-tarmac fun.

Back over Arthur's Pass to Darfield, Geraldine and Fairlie. Stayed the night at a Fairlie camp ground. Met 2 other bikers. One was Peter Steadman from Te Puke (GPz550) and his mate Carl (XJ1200?).

2009-12-07T11:16:00.000+13:00

Wednesday 25th November 2009

Left Home at 6:10am. Went via Poripori Rd, then out along Oropi Rd.

Stopped at Dave's to grease the suspension. I also dropped off a dish washing brush as whenever I do the dishes there, they never have one. I also wanted to ask Dave about the roads around Ashurst. Their place looked pretty quiet at 6:30am so I didn't knock on the door and wake them up. I left the brush but forgot to grease my suspension. Meh!

Oropi Rd onto Mountain Rd and No. 2 Rd to Te Puke. Then out to Paengaroa and along Old Coach Rd an onto Matata and Edgcumbe. Then through Te Teko and Murapara. I stopped off at Lake Waikaremoana and had a pie and a banana. Then on to Wairoa and Napier. Then on to Taihape, nearly running out of gas.

Taihape to Mangaweka and Cheltenham then Ashurst. I then went over the saddle Rd to Woodville and back towards Palmerston North along the gorge road. Then I turned off at Ballance Gorge Rd and went along Hall Block Rd. The signs said No Exit but I thought I might be able to make way through anyway. After about 15 km of extremely gusty gravel road I came to a locked gate and had to turn back. Extremely strong winds! Nearly could not ride along the gravel as the wind just kept sledging the front wheel sideways to the edge of the road. Had to travel very slowly in first and second gear.

After this little dead end side track it was about 7:00pm so I just took the main roads down to Wellington over the Rimatuka's.

Arrived at Pete's place 9:20pm. Got to sleep at 11:00pm. Woke up at 1:00am and went down to catch the ferry.

Burt Munroe Challenge: Preparation

2009-11-24T16:45:00.000+13:00

Tuesday 24th November 2009.

Well, I entered the Burt Munroe Challenge online.

$50 entry and 2 cooked breakfast (Sat and Sun Morning) at $11 each. $72 total.

Then I booked a Cook Strait Ferry crossing getting a BMC discount. $73.

I am allowing 3 days to get to Invercargil.

Two days (Sat Sun) at the rally.

Then 3 days to get home again.

I expect to take in a LOT of gravel and out-of-the-way roads.

I got a new Mitas E-09 rear tyre from LMS in Palmerston North $160 incl freight. The odometer showed 53774km at tyre change. I love these tyres.

The old tyre (also a Mitas E-09) had 5mm of tread depth left, so I may well use that again at some stage. The old tyre was put on at 48365km. So has done 5409km for 9mm of wear. (601km/mm of wear) This is about 170km/mm worse than the previous 2 E-09's. Hmmm?

I got Wobbly to weld an enlarged foot on the end of the side stand just so that it doesn't sink into the dirt as much.

The carbueration on the XT400 was still not all that good.

I got two 100 main jets off a friend Jared and I borrowed the needle out of the CV carb on a mates TT600. I put them in and the bike went the best it has ever gone. It was a little lacking in bottom end but was very good in the top end. I was happy enough for now.

I took it in to Smithy's for a warrant of fitness; $28, and registered it for 3 months; $86.

I also bought a pair of black padded Lycra cycling shorts for $70 to wear under my leather pants. I hope these help to make the ride a bit more comfortable.

I bought 4 AAA batteries for my torch $9.60.

I also filled up with 98 octane from BP. This was a little interesting. I was carrying a 2 litre jerry can in the rack pack and was on reserve tank, so was not worried about running out of gas. It just so happened that I ran out of gas on the downhill approach to the Te Puna BP. So I was able to measure exactly how much fuel the bike held. To fill it up to the absolute top from completely empty (even the carby bowls empty) took 13.9 litres.

Yesterday I did about 100km and today I did about 70 km on the bike just to make sure everything was OK. And everything did indeed seem OK. Cool.

Well actually, ever since I had the tappet cover welded up, the RHS exhaust tappet has ticked quite loudly. I have checked and re-checked the clearance. I also tightened the tappet up until it stopped ticking, just to see what it would take. When I did this, the bike became very difficult to start and would not idle at a low rev. Hence, the exhaust valve was probably always open a little. I will just put up with the tick.

I will head off about 5:30am tomorrow morning. 53943km currently showing on odometer.

I will go via Waikaremoana, the Napier- Taihape Rd and eastern Waiarapa to Pete's place in Thorndon, Wellington. This will probably take a full 14 hours I expect. I will have to get up at 1:30am Thursday and get on the 2:30am ferry crossing. Arrive Picton 5:30am. Yes, I am on a mission.

Back together after rebuild

2009-06-08T17:09:00.000+12:00

Sunday 7th Jun 2009

Yesterday I went to see Tim. He had the engine all back together after getting the cam back from Kelford cams.

We put the engine back in the bike. The new carbs fitted in perfectly well. It was quite surprising.
Just as we were starting it up we ran into an electrical problem. It was very difficult to track it down and lead us on a 1 hour goose chase, but Tim discovered that the positive battery wire was not quite making good contact where I had attached it to the battery. D'oh!

The bike seemed to be running quite lean at low revs and Tim later discovered that this was due to the vacuum petrol tap hose (not present on XT but was part of GPX configuration) just loose and letting in fresh air downstream of the LHS carby. This was easily fixed by bunging it up.

The bike now seems to grunt quite well at low revs and low throttle, but the jetting just strangles it anywhere else. I need to make some jetting and needle changes.

Just for the record, the standard Keihin 30mm CV carbies (of a GPX250, Model No. CVK EA24 V592) are jetted accordingly:
Round type main jets 108
Pilot jet 38
Emulsion tube, No Numbers
Needle N16I (Quite a weird needle in my opinion as it tapers of very sharply in the last one fifth of the throttle as the CV carbs open right up.)
Mixture screw,.. I haven't checked it yet but it has been wound in 2 full turns from when I first got it from the wreckers.

Note: The CV carb on the original YDIS setup has a 32mm ID at the intake to the head. The mechanical throttle slide carby on the original YDIS setup has a 30mm ID at the intake to the head. However, both of these carbies have a smaller oval shape to then at the actual throttle slide.
The YDIS mechanical slide carb has:
Round type main jet 108
Pilot Jet 48
Needle 5D90
Emulsion tube V00
The YDIS CV carb has:
Main jet 96 (not 95 or 98,.. I double checked with magnifying glass as 96 is an odd size)
Pilot Jet: there is none
Needle 5Y15
Emulsion tube 90

So I am immediately tempted to try the new GPX250 carbs with:
main jet 108
pilot jet 48
Emulsion tube, not sure
Needle: something similar in profile to the 5D90

I might put the bike on a dyno with an exhaust CO meter to help get the jetting right.

More to come once the jetting is sorted.
We spent about 5 hours on the bike on Saturday (11am - 4pm)
On Sunday we went to the Airshow and worked on bike for 3 hours. (approx 1pm - 4pm)

Engine Rebuild

2009-05-17T15:17:00.000+12:00

Well, the XT started to lose power.
I noticed that the it was burning about 500ml of oil every 1000kms and there was a bit of oil starting to accumulate in the air box.
So I am ( well, Tim is actually) now in the process of a full engine rebuild.

Piston:
I wanted to get a piston that would take it out to about 450cc but after looking around couldn't find anything suitable so just settled on a standard Yamaha piston at 0.5mm oversize. (Now 87.5mm bore)
Piston $198.19
Rings $79.47
Gudgeon Pin $36.95
2 x Circlips $4.20
I did think about using the piston out of an XT600, but after much deliberation decided against that.
The bore was bored out to match the piston by Regal Automotive. ($120)
The piston has exactly the same part number as the SRX 400 piston.

I talked to a guy on the KiwiBiker forums who has tried modifying an XT400.
See this link: http://www.kiwibiker.co.nz/forums/showthread.php?t=7362

Carbies:
I have bought a pair of Kiehin CV carbs off a GPX250 from a wrecker in Upper Hutt. $250. These have a 30mm intake diameter and should be significantly better than the standard YDIS carbs that have an oval shaped intake about 30mm x 18mm. ($260)

Apparently the GPX250 carbs work well on SRX600's and XT600's. I'm hoping that they will be OK on the 400 also but time will tell.
Here is where I found out about it:
the second to last paragraph for Question 3 at this website: http://72.14.235.132/search?q=cache:amUBgpOBxz0J:www.thumperpage.com/articles/srx6faq.html+gpx250+srx&cd=2&hl=en&ct=clnk
They do fit pretty good! Just had to stretch the LHS upsteam rubber manifold to fit and swap cables over to the RHS of the bike. And just had to slightly bend the rear brake fluid reservoir bracket a little bit to give clearance on the throttle cable twist on the carbies.

Reshape Cams:
The camshaft is being modified by Kelford Cams in Christchurch. ($315) http://www.kelford.co.nz/
I am just hoping that they know what they are doing.
My instructions to them are basically: It is a 1992 XT 400 and probably revs to about 9000rpm. Do what you think. [Actually Tim asked to have the lift increased by 0.5mm]

I guess they will just do a standard re-profiling to give a more modern cam timing.

[The 50 thou duration on both inlet and exhaust was increased to 229 degrees, (from what?)]

Head work:
Tim has ground away at the head to get a nice air flow path. He ground the valve seat stems back to the body of the head and will just use a thin section of the old head gasket to increase compression slightly.
Also there was a crack in the top of the rocker cover which was seeping oil. This has been welded up by Regal Automotive (~$40). The crack was due to stress from the top engine mount I guess.

Flywheel:

Tim thought the flywheel was pretty excessively heavy so he machined it down to what you see in the pix. Pity I didn't get a "before" shot for comparison.

Exhaust Header Pipes:

Tim ground out the weld bulge in the inside of the header pipes where they join onto the head for slightly better flow.

Misc:
New bearings throughout engine. Cheap.
Cam chain $80.23 + gst
4 x valve stem seals $32.50 + gst
Oil filter ~$15.00 + gst
Gaskets:
Base gasket $32.08 + gst
Cam chain tensioner gasket $ 7.47 + gst
Crankcase gasket $24.33 + gst
Another crankcase gasket $20.13 + gst
Oil Seals:
Oil seal 25 x 40 x 5 $9.44 + gst
Another seal $8.21 + gst

Piston, rings etc + seals and gaskets came to about $610 all up incl gst.
Rebore and welding $160
Cam Mods $315

Oil and new Plug $70

Total: $1155-ish plus I'll have to sort Tim out.

I also tightened the spokes on the front wheel as they were all a bit loose.

I broke 3 spokes in the process so will need to get 3 from the wreckers and fit them.

I am thinking that if it used to have about 20 - 25 horsepower, then after this work it may get to about 30 hp after I get the jeting and needles sorted in the carbs. Well maybe.

More to come once it is all back together.

Sam's 40th - Day 4

2009-03-17T12:22:00.003+13:00

Rode back to Tauranga

Left Puniho 9:30am and went to the rhodedendron gardens at Pukeiti ($14)

Spent about 1.5 hours there.

Stopped at the Centre of the North Island in the Pureora National Park. [Photos to come]

Then on to Tauranga

Got home approx 9:00pm 53387 km

Rear brake pads were toast when I got home.

Bought some new EBC "Fusion" pads from Bayride ($53). EBC Part No. FA101TT

Advertised as "New Carbon Graphite "Tout Terrain" or TT" pads.

Supposed to "run cooler making them ideal for MX and ATV"

"Tout" is basically French for "All". Hence, - All Terrain
