Idle is good An it shifts fine when cold just won’t shift once warmed up unless I shut it off. Once it warms up it starts to idle itself up higher like the throttle is stuck open
I have a 2008 Yamaha grizzly. Once it’s warmed up it won’t let shift out of drive or reverse it’s stuck in whatever gear I had it in unless I shut it off. It’s runnin warmer then it should An isles up as it gets warmer
