Hi All, I bought an 83 with twenty thousand miles on it. I am experienceing a problem with the engine makeing burp noises and emitting smoke around the tank filler area. The smoke is blueish, like it prolly is crankcase blowby or would be similar to the exhaust of a car that is burning large amounts of oil. This bike does NOT emit blue smoke from the tailpipes at all. The burp sound, and this emission of smoke, typically happens at low rpm, maybe no more than 2500, under mostly very light to no throttle. The first times I heard it, there was just a burp noise and the emission, but the last time it happened, it was substantially louder, and there was a hiss at the end, along with a larger amount of smoke. I was travelling about fifteen mph in second gear, and it just happened. My impression is that this must be a build up of crankcase pressure, that somehow gets forced out thru the cc vent, into the air cleaner, then perhaps the air cleaner assembly has a rubber seal that is disturbed enough to make the burp sound, and separates releasing the built up crankcase pressure, or at least this is what I think. What think ye all, please.
