So a few weeks ago i went to start up my bike for a ride, and after it idled for a while i took the choke out and it died. This has happened to me before, and i just thought that it was a gummed up carb that i would have to pull of, clean out and put back on. I then noticed that there was oil leaking out of the bottom of the air box underneath the tank. This was cause for some alarm, so i began to take the bike apart.

I was worried that the leak had been occurring for a while and i hadn't noticed it, so i drained the oil tank to see what the condition of the oil was, and the crank case had been filled to the top with oil and fuel.

I have no idea what this means. I have pulled the carb and cleaned it up, but i am not sure that this is going to fix the problem.

Any suggestions?

Your vacuum operated petcock has given up the ghost. It basically allowed your fuel tank to drain into your crank case.

Replace the petcock. Then do a whole bunch of oil changes, with cheap ass oil, to get the fuel out of the crank case.

You have two problems. As mentioned, the fuel petcock is not working, plus you have one or both float bowl needles that aren't seating. Fix the petcock and disassemble and clean both carburetors.

Once that's done, refill with clean oil and take a ride, at least an hour. You don't have to repeatedly dump the oil.
