I have to disagree with you on this. My 800 and others have been know to be at min, 2 sizes off. Stock is 430 mains. People have been known to go as low as 380s in the 800's. Also. I really don't see why you would ever have to run premium with rejetting. Makes no sense. Your not changing compression or anything. Don't want to start a war here but lets not give Mike any incorrect info. I have come to know and trust a lot of people on this site. Let's keep it that way. :thumbsup:Originally posted by zeng62@Dec 11 2002, 03:22 AM
What sled are you riding, jetting down too much can burn a hole straight through you piston, arctic cat jetting is close from the factory, be careful, if you do jet smaller on the main jets use premium fuel.
