Topic: Shooting for Spring

[bkalasin]

Have spent the last six months avoiding the garage housing my 1972 CB750. Bought the bike about 18 months ago and began to have compression problems. Decided on a partial rebuild- rings and gaskets (and a new wiring because I had never done anything remotely mechanical...if I'm planning on a headache, I'm planning on a doozy). After several setbacks along the way, I eventually got the bike up and running with the help of several kindly folks here.

However, I immediately found that I was weeping gasoline from the breather tube attached to the rear of the head cover which would turn to a fine mist that coated my rear wheel and made the slighest turn an adventure. Accordingly, the bike has about a whopping 10 miles on it post-rebuild.

Springs coming and I'm hoping to reclaim my manhood. My question: I had not yet went in to check/readjust valve clearances since the engine went back in the bike. Is this possibly my culprit or are there several other things to check out first? Any suggestions would be greatly appreciated.

This is a guess.....  If it's actually gasoline that's coming out of your valve breather I would suspect that your carb bowls are overflowing, when parked, and gas is getting past your piston rings and into the crankcase where it mixes with the oil and gets circulated back up to the head. If it is gas then I would suggest you not run your bike at all until you get the problem sorted out and have drained and replaced ALL of the contaminated oil.

     I can't see how a improperly adjusted valve could result in having gas in your oil.
