Observed Trials Tech

So what's this all about? It's about trials and making your trials bike perfom better. This blog is to share ideas and expose trials riders to technical improvements for both modern, vintage and twinshock machinery.

ITSA Project

While sitting around looking at the bikes and projects scattered about the shop Pee Wee and I got the idea to turn the TY250 he is riding into an ITSA Modern Twinshock bike.

That's the class that allows anything aircooled, drum brake and twinshock.
Not everybody (in fact most of us), Have a complete machine shop that would allow one to build a bike for this class from scratch. ITSA knew this when it formed the class and planned for both one off specials and upgraded existing machines.

We are going to start with the machine in the picture. To date it has some engine mods which include an electronic ignition, B&J's intermediate porting, Boyesen reeds with B&J's mod to the cage, B&J's Mikuni carb kit and a B&J alloy skid pan. Guess you would have to expect all the B&J mod's...it's The Guru's practice bike.

Planned changes are to install the exhaust The Guru modified for the famous blue TY he currently rides. We may play with some different carbs that have proved successful on other projects. The big change will be in the suspension as we plan on installing a set of forks from a TY250 mono shocker along with the front wheel from that machine. The rear suspension will receive an upgraded set of Falcons similar to the ones that were built for the TLR200 Hockeyboy rides. We are also going to install the TY250 footpeg lowering kit that has been sold every time we had a spare!

We will keep you up to date on the project!
Pee Wee is already a candidate for the Nubbie on this bike!

    Yo Guru, I loved that line that you used, "the exhaust The Guru modified for the famous blue TY he currently rides." Why didn't you just go ahead and say "the cheater bike" and then everyone would know of which machine you speak. ;-)

    Well I didn't say "the cheater bike" because I wanted you to know which one of my bikes we were speaking.
    As you know ALL my bikes have been accused of being beyond the spectrum of legal. When in fact they are...legal!
    I'm still trying to figure out which Yamaha piston and crank fits into the Villiers cases! I sure wish those who accused me of this infraction would let me know which one they are using, especially if it is so much better than the stock O.E.M. parts I'm using!
    Just imagine what the James could do then!
    The Guru
