while riding my grizzly i go to give gas it starts popping back firing and it loses power. but it only does it once in awhile. i'm wondering what causes this.i'm thinknig maybe the sparkplug. or its the carbs.anyone have any imput. sucks this time cause i was in a deep mudhole and it acted up and cause me to get stuck....but if i let off the gas and let it idle for a minute it goes back normal...got me confused

You'll probably have more luck going to www.grizzlycentral.com and giving more details such as what year yer Grizzly is and which model...

Probably the reverse overide- I by-passed mine- no problems now.

The override is for when bike is in differential lock.

could be shit in the carb, or could be jetting problems?

you might want to check the connection on your front diff, it is on the lower left side of the bike it acts like a govener which only allow your bike to go no more than 25mph or short burst of speeds like when it is in diff lock, check to see if it is loose if so put some die-electric grease in there and make sure it's tight let me know if that helps

I am sure this was what was going on. Just a saftey feature, push the green button and hold it, Problem solved.

Could be be dirty fuel My quad has the same problem as yours

Yeah well you have a arctic cat. Jking, my friends dads grizzly 660, the new ethonal shit corrodes shit so it corroded the seat in the carb so when they got a new one, (seat) put ethonal blended gas in it and it did it again. So... ethonal corrodes shit so try not to use it
