I have a question concerning my jetting. I'm in Ohio, elevation from 900 to about 1000ft. The needle and needle clip position are stock, air screw is 1.5 turns out, 155 main jet, and 55 pilot jet. The plug is alittle on the dark side but the bike runs great, doesn't foul plugs or anything. Theres a mix of woods and open areas where sometime I can get up into 4th or 5th gear. With the stock jetting the bike would foul plugs even when opening her up. When I first got the bike I ran MC1 @ 50:1. After changing jetting and the advice of a friend who owns a local shop I switched to Maxima SuperM @ 50:1 and like I said, haven't fouled a plug since but have a darker than normal plug. My question is, if I raised the clip one position would this lean out the carb over the entire range? I really don't think my jetting is that far off, don't feel any blubbers or anything, just the plug color. Maybe I should leave well enough alone? Thanks for any help.
