So yesterday I installed a DOT head onto my 2003 b12s. I'm running a dale walker stage 2 kit, k & n pods, yoshimura can/mid pipe ( the midpipe leaks at the connection with the headers possibly causing a lean fuel mixture). No advance on ignition. Valve clearances are set to spec. PAIR system removed. I have low octain gas in the tank at the moment and I just did an oil change. It's 90+ degrees here and above 85% humidity. When the bike warms up the oil starts to steam from the crankcase breather and the oil fill hole (when I remove plug). It also will not start. The motor turns over really slowly in a chugging fashion. The more I try to start it the slower it chugs until it just stops. The battery is just above 12 volts. I'm also getting some pre ignition or detonation ( I'm not sure which one) when it's hot and under heavy load. Any ideas? Am I running too lean and overheating? Is it my starter overheating? Is 11:1 too high for such hot weather? I'm guessing the low octain fuel is the source of my ignition issues.
Thank you in advance! This is the first time I've needed to post anything but I have always found a ton of useful and well thought out info here.
