I just tried to do the free mods to my '02 WR426F and I just got the throttle stop bolt out. Apparently the dealer had already cut it off. However, they cut it off all the way down to the threads. All of the links that I have checked out to make these mods tell me that I need to leave 20 mm on the stem. I am just curious about whether this matters, and if there are any affects of having it so short.
