This thing seems to run great when trail riding for an 30 minutes to an hour, then begins idling very fast. The first time it happened I couldnt even put it in gear. Then I remembered that I could start it in gear so I turned off the engine and put it in gear then restarted it. After riding this way for 5-10 minutes it went back to a normal idle. Its done it 3 different times now. Any ideas? Thanks!

Also, blipping the throttle doesnt help and turning it off and restarting does not help. My Grizz has a carb. Not F I.

Check the carb to head rubber boot for cracks and tight clamps. Sounds like an intermittent air leak is leaning it out and causing high idle speed. If needed, check carb pilot jet for debris/junk.

I start it up and while it is running I push pull and prod on the rubber boot going to carb and all other rubber hoses running to carb. Nothing makes it duplicate the revving. So I guess I need to have someone go through my carb next?
