After much more hours that I planned (I do not want to expend too much time on the NSR) the cylinder it´s already modeled in 3D with Solidworks. Some parts seems like if they challenging me to do them on 3d, and the top end of the engine from my NSR it´s one of these parts. I will model the top end of the engine while I´m working on the little two stroke Honda only like a "personal

   Yamaha TRX 850 concept by Tomas Byrom. Good looking concept that combines the TRX 850 with the fairing from the MT-OS .Never I´ll understand why Yamaha do not release a NEW  YAMAHA TRX!! If you think that Yamaha must make a New Yamaha TRX you can join the group "We want a new TRX" in Facebook.

Santiago´s Yamaha SRX 600 and Paco´s TRX behind, Montanejos road it´s a good spot to ride and every weekend a lot of riders of Valencia and Castellon area comes to ride to this beautiful town with twisty roads to enjoy. Usually I take some photos to all the bikes that I like, cafe racers, twins,

Following with the overall checking of  my Honda NSR 125 I was dismounting the engine top end of the engine to check the cylinder/ piston and dismount the exhaust valve to clean it. The cylinder head needs be cleaned and polished. The cylinder seems in good condition, for the moment I do not will boring it. RC Valve axle and seal ready for being removed..... ......but when

After last works done on David´s Vespa, we are on final stages of the rebuild and now we´re begin thinking on the aesthetics or tunning  the little vespa. For the moment , the sport seat from SIP it´s mounted unpainted to able David ride and test how works the Vespa. But last week we mount one of these things that not give nothing essential (talking technically) but after work a lot with, the

Along the general check I´m making to my Honda NSR 125JC20 that I bought not much time ago, I´ll need the tools to mount again the new clutch disks ,or not (read THIS post), because the lock nut was loosen but anyway I´ve the new ones.... To build the tools needed I sketched them and bought a 1/2"-17mm socket wrench to build the lock nut wrench. I choose it of 17 because it´s Ø24 just that

Do not know why, but I don´t  realized I had one of my  pieces included in the 3dvia top ten #140 last November. Isn´t the first time one of the parts that I modeled in 3D are selected to one of the 3Dvia top tens but always I´m glad of it. This time the part "awarded" it´s the Yamaha R1 lower yoke that I published last October and I mounted on my TRX with the R6r upside down forks.

After dismount the clutch from the engine and disconnect fuel and coolant pipes I get off the engine to have it ready on the workbench  for dismount and clean the RC valve. I did it helped with a car stand and because it´s a little engine I could  load with it alone. Carb and engine out!!. Now the NSR becomes a bicycle. But it not will stay without engine for long time.

The Yamaha TRX 850 always has been used as a good base for Cafe Racers (The guys from  TWIG TT also does great CR kits for Trixies) but this faired Trixie done by the crew of Mutiva Moto Center from Mutiva Baja , near the city of Pamplona (Spain), got a look different from other Cafe Racer conversions. The Norton Comando fairing of the 70´s fit like a globe on the TRX and looks sooooo gooood!.
