Finally getting this thing put back together, it seems to idle like on the limiter. It clears up when off Idle, and the etc switch is not depressed. I'm assuming the reverse limiter is the culprit. I've seen different threads with conflicting fixes. Is it the box with 4 wires, or is it the box with 3 wires? Then what do I do? It also Idles ok with the reverse button pushed. I've read that you cut the black wire, but am unclear. After confirming it's the reverse limiter box I will be buying a new one, the kids will be riding this thing. Also it is a 2x4
Thanks, Doc

 

Hey .. i have a trail boss 250, i sorta noticed my bike does that too, it revs up and back down i tried settin the idlein up but nothing, i never tried the reverse button. hopefully somebody will give u some info so i can get sum info on it and fix mine too

 

It is the box with 3 wires.Follow the wires back to the connection block and unplag the black wire this will disable the unit.
