Coupelx Posted February 18, 2012 Report Share Posted February 18, 2012 So rather than send you on a wild goose chase.... Your plug days its rich. Drop the main a size at a time and go for a rode and note the difference in how the bike feels. CHANGE ONE THING AT A TIME. This way you can tell what it wants.

Jonny72888 Posted February 18, 2012 Author Report Share Posted February 18, 2012 I just checked my jetting and I guess I had a 280 main in it and not a 290. Should I just jump down to 260? Or should I go buy some 270s. Like I said before I was having over heating problems at low trail speeds. The main shouldn't affect that right? The problem happens starting at a certain rpm at wot and stays the same through the rest of the rpm range. Quote Link to comment Share on other sites More sharing options...
