Im putting together a 4mil trail port shee. Tors removed, aftermarket pipes and silencers. I have No Idea on the brand since there is no marking on silencers or pipes. Pods filters with outerwears. Premium pump gas. Sea level to 1500 ft elevation. Its going to get cold here in the PNW so I know that needs to be accounted for. 25 pilot and 260 main is what are in the carbs. I was going to go 28 on pilot and 300 on mains and tune a little rich. Does this sound right? Where should i buy jets from? Thanks guys
