On my 00 Sporty 1200 Custom, i'm having excessive fuel blowing back on my oil ressy when i'm out on the highway, at first i thought it was blowing it by the back cylinder, but today i took the air filter off and thats where all the gas is coming from, the cover was soaked and so was the filter, anyone have any ideas what it could be, maybe a jetting issue?

 

If your engine is coughing or sneezing out the carb you would be surprized how much fuel gets pushed out and sets in the filter. if so get it jetted and tuned and you'll notice a difference. You could also have a leak in the fuel line and with the vac operated petcock you won't see it til you ride it. just my .02
