Has any one experienced needing a larger main jet in a Grizzly due to a top speed miss.If so what size of jet did you use.

 

I wonder if you really need a larger main jet or if you are just overreving your machine? My guess is that you are doing the latter. If your machine has the stock jet that was meant for sea level, my guess is that you are just bumping the rev limiter(if the grizz has one??) or floating the valves. Either way, i would refrain from doing so in the future.

 

I am down about 10 miles an hour on top speed,iam wondering if one of the clutches are not working properly,I replaced the belt,and inoticed the wear marks on the drive(primary)clutch were about 3/4 of a inch from the top of the clutch,any one know how high the belt should ride when shifted out.

 

Thanks for info,it was the primary clutch,not shifting properly,the grease was mixed with dirt and dogfood,that a mouse hadbrought in.
