so as many of you have probably realized, i had a huge thread regarding my yz250 about a month ago. Well, all is good! Just had a little question... When i have the clutch pulled in, and i give it a pretty high rev, i can feel it BARELY move forward (or at least try to). It doesn't stall, and it doesn't lurch at all. Just barely tries to move forward. Enough to grind my gears... pun not intended. Does this happen to anyone else? is it just the vibration of the bike? Doesn't try to do this unless it's a high rev.
