Darn, how unfortunate. Look into White Brothers, they have a great assortment of lil' thumper products at reasonable prices.

I hear somebody is going to produce some hot cams for the 426. Also, the accelerator pump on the FCR carb can be modified to eliminate possible rich bog when opening the throttle fast. I think you can also go as far as getting a big-bore kit.

Oh, you were talking about the TT-R? 90 or 426, little buggers all :confused:

Does anybody know if there is any restrictors on this bike to keep in under control ... rev limiter - exhaust restriction plate . Any hidden mods that a guy can do without tearing into the motor . It is an 01 and I will probably sell it after this riding season but dont want to go overboard taking the engine apart.
