Sorry for the rookie question, but i was just curious to know what a throttle stop does and if i have one on my 2002 YZ426? I bought the bike used a few months ago. I read a lot of posts about the throttle stop on the WR's so they could make them faster, etc. Just curious as to whether or not my 2002 YZ426 has one and if mine has already been messed with. Or what i can do to change it, etc. Seems fast enough already. Anyway of making it less powerful? Thanks for helping a rookie out.
