I saw a previous post regarding this but no follow-up. My bike is stuck in 4th gear and will not shift down. I think it will shift up because I had my friend Howard take a look at it and he was kind enough to shift it from 3rd to 4th for me .Made for an interesting ride back to the truck . Luckily these bikes have got some bottom end. The bike is under warranty so that won't be a problem. Just dreading the down time. Anybody have a similar experience.
