at the end of last year my sled would bog bad some times you could burp it over the bog I put a new belf and about$400 in clutch work my jet setup is 340main 27.5 needle clip #3 and it sounds like its dropin to one cylinder just got a new coil SOMEONE PLEASE HELP

I had the same problem, finally tracked it down to carb slides. They vibrate and crack, check yours very closely.

Jet down quite a few sizes my friend. I'm assuming your on pump gas heads and still that is wayy to fat.

Ya iam on pump gas what would be a good steup

im running 330s and mine stil bogs abit but the plugs are the perfect colour so i dont kno if i would want to go any lower

one of my buddies was taging along with a polaris race team and he said thouse motors like to run lean but ya my plugs look dark and my carb slides are trash
