Sled moves forward without pressing throttle

All good info...had a buddy that had buildup on his primary clutch where it slides for engagement/disengagement... a good cleaning helped alot for him.

Update - so i think removing the shims and changing to a yamaha belt have corrected my issue. I can let the machine sit and idle without it pulling forward. all good now! when the new belt tension bolts and shims come in, I will see if they make a difference. thanks everyone!
