my grizzly 700 restricts itself and puts on the reverse light when it gets hot going forward not continually but every quarter mile or so , have changed the speedo sensor and checked all the wiring as good as possible , have earthed reverse wire to engine as a temporary fix but would like to know the cause ..... thanks ...taggart

 

You may want to ask over here. It looks like their review crew entails 3 Grizzly 700's, a 660, and a Rhino. Certainly they could help you faster since it looks like this board is more into sport quads.

 

got to the bottom of my restricting problem it was a faulty reverse switch . had the very same problem on a 660 grizz the day after and it was the reverse switch on that too . thanks
