I've noticed that my throttle on my 16' YZ450FX takes a lot more to twist verses my prior KTM or some of my other buddies bikes. When I was at the National last year, Corey McDonald felt it was fairly tight too. He suggested I clean it and see if that helps. I did and it's still tight. Not ridiculously tight, but enough to cause fatigue during a hare scramble (I know... I know, I sound like a wuss! haha). Almost like the return spring is too tight. Is there a fix for this? Anyone else have this issue?
