raptor 660 hard upshifts

[intimidator]

I recently sold the 200x and bought an 01 raptor 660. I love the thing, but it shifts a little stiff, especially upshifting. I don't have much of a problem, but my 10 year old son usually can't get it out of first gear, (under CLOSE supervision by the way) and he never had a problem with the 3 wheeler. I've heard switching to synthetic oil will help this. If so, what weight and brand should I go with?

Thanks, Jason

An 01, huh? Has it had the tranny updated yet? Hard shifts could be a sign of trouble headed your way. While you're at it, you should replace the one-way starter clutch, too.

damn yamahas!!
before all the headaches try adjusting the clutch
do you need new fiber plates?
did the other owner race it? ,or was hard on the clutch
-sorry other than that there could be a lot wrong? i am not there
your son is young is he pulling the clutch in all the way
just suggestions

The '01 raptor is famous for the tranny problem. I don't know the details but there is a recommended upgrade to fix the problem. Look for a raptor specific website/forum and ask there
