I'm new to the forum but have been reading for awhile and have learned alot. I have a 04 grizz660 with a k&N filter and I am looking at either a pipe or a new high flow exhaust tip. Do I need to re jet? I run in sub zero weather at times. Is it difficult to re jet? I have been re-jetting my sleds for years but it looks a little more involved with the grizzly.

 

I have a K+N filter and a high flow tip on my Grizzly and I did'nt need to rejet. The Grizz comes from the factory WAY too rich and the combo I run leans it out perfect. Now, if you get a full system then I'd rejet. Heres a link to the tip I bought on Ebay Exhaust tip....Ebay
