TY 250 improvements

Postby yamaha man » Tue Aug 28, 2012 6:43 pm

Hi I have just purchased a 1984 ty250 trials bike as a project then to enter in clubman.

I am looking to do some improvements and was wondering about what sort of improvements are doable to improve the bike.

I have heard about moving foot pegs, increasing rear shock length, some throttle mods to change it to a 1/4 throttle along with flywheel mods and big boring with a dt piston.

Are these mods good or bad and what are the measurements if they work well.

Also any other modifications you can think of would be appreciated.

thanks

I was thinking the same.

If it is a Mono there is only one thing that I could suggest that could improve it but we are not meant to use bad language on this forum.
I will suggest you forget about 1/4 turn throttles and big boring etc, just return it back to original condition and learn how to ride it as it would be more than good enough to win Clubman on.
