hi, i have a 2005,bullet with a 535 engine in it,i have tried a few air cleaners on it but the ace air cleaner is the best, any way what i would like to know from the mechanically minded is how is the best way to seal the crank case with out pulling the motor apart, the bike is a panther 600cc ,m100.the oil is pouring out from the top of crank case . i have cleaned out the crank case breather valve so that is working . thank you.chonpuun
