Josh here from the sunny state of FL. I'll start by saying that I've been maintaining my own machines for 30 years, so I know my way around an engine. I've always had chain driven sport quads though, my only CVT is on my Rhino, and I've never owned a Kymco. I just bought an 09 MXU300 as an upgrade for my son for a steal. It's super clean and starts right up, but will only go into reverse. I pulled the linkage off and shifted the transmission by hand. It would still only catch reverse. When the machine is off, I can put it in H or L by hand and feel/hear the transmission spinning. Neutral works fine. If I hand shift it into H or L when running, it rolls like it's in neutral. If I add throttle, there is no noise or movement. If I roll it forward or back with slight throttle while in gear and running it sounds like something is binding. I'd appreciate any suggestions before I start tearing it apart!
