I pulled my plug a while ago and it was sheet white. I am running 110 octane low lead (76 brand). I was runing the stock jetting (03 bike). Looks way to lean to me but it seems to run great. Changed the pilot jet to 45 (42 stock) main jet from a 170 to a 172 and put the needle in the 5th position (4th stock). After that it idles like crap and died when I gassed it so I went back to stock on the pilot. Everything seems ok now but havent ridden it yet. I know the "proper" way to jet your bike by reading the plug is to kill the engine and pull the clutch at different trottle settings then pull the plug and take a reading but no way am I going to take my tank off on the side of the track to check my plug. Anyone else have to richen their bike up when running race gas?
