Thanks HLT, I didn't think of the float height. THe more I think about it that might be the problem. I'm getting cold plug fouling . When I change plug it's very wet, not so much oily but wet. I'll give that a try. I'll give you my jetting changes. Main went from 172 to 168, Pilot stock 48 went to 42. praticed Wednesday night, fouled aplug at the beginning. New plug , bike ran great all night. Thursday washed the bike, started it after washing, fouled a plug.I dropped the neddle one groove, but haven't tried that yet. Any opion's are appreciated.
