does anyone know if there where any changes in either the carb or throttle assembly in an 00 426 vs. 01 426? The reason that I ask is, I rode my freinds 01 and the throttle pull is super light compared to my 00. I went home and completely cleaned the carb, new throttle tube, lubed and cleaned the cables and it is still twice as heavy! Anyone have any ideas? I never noticed it before I rode his bike.
