Infamous039 Posted May 31, 2012 Report Share Posted May 31, 2012 If its running lean I would raise the mains up to 300-310. Also check for air leaks as well before you start chasing jetting. Quote Link to comment Share on other sites More sharing options...
fastbshee Posted May 31, 2012 Author Report Share Posted May 31, 2012 Ok thanks I'll give it a try Quote Link to comment Share on other sites More sharing options...
bluebanshee98 Posted May 31, 2012 Report Share Posted May 31, 2012 did u do a plug chop to verify that the bike is running lean? 290 should be just fine with airbox lid off and after market air filter. it sounds like you have a leak if the plug chop says its lean. 310's are usually used when u have pods and the engine is not ported depending on elevation.
