I want to put a quarter-turn throttle on my '04 xr 650r, the half turn has me choking up each time I want to give it full throttle, which makes it tough to get back off of the gas quickly. That and when I do give it full throttle, it's tough to keep my elbows up. The result is that by the end of something like the Baja 500, I'm too tired/lazy to keep giving it full throttle out of the turns. Has anyone done this? Does anyone know if a crf 450 throttle tube will work on the bike? I have the Edelbrock carb. Thanks for the input.
