Hello everyone,

Im new to posting anything but have been reading alot of helpful info for many months now and i have to say thank you all!

I have an 07 Grizzly 4x4, I have had for a few months now. I bought it used so Im not sure how it was used previous to me. My issue is that sputtering /spitting that i have read that grizzly is some what known for. My issue is that in some mud not even to deep and going up hill it seems to loose power and start that spitting / sputtering. Its the same feel and sound as the reverse limiter. Can any one help lead me in the right direction. below are the things that I have done trying to correct the problem.

*spark plug, air filter
*cleaned and rebuilt carb with new jets (this seemed to help a little but could have just been my imagination)
*reverse limiter bypass (this corrected the problem in reverse but Im still having the problem in forward, but this also seemed to help the grizz run longer in mud or up hill before it starts with the farting.)

Any comments will be much appreciated.
