I have had this problem for a long time now. Fuel in the oil.
I have done many things to remedy the problem but nothing seems to work. I'll start you on this journey of mine with some info. I have a 1981 xs650 special with 30,000 miles on it.
I bought the bike hoping to turn it into a bobber/chopper of some sort and over the 2 years I have owned it I have done just that, with very little troubles except for the fact that throughout the entire time I've owned the bike it has leaked gas into the oil.
So here is what I have done so far. As a warning other changes were going on with the bike as time went on that might effect my problem but I'm not sure. I'll mention what i think is relevant. Also I replace the oil after each failure to fix the problem, also most times gas leaked into the oil while the bike was sitting over night. It was only ever the contents of the carbs never more than that each time.
- Bought bike and found gas in oil.
- cleaned carbs witch were dirty. still gas in oil.
- set float height to manual specs. still gas in oil.
- replaced floats, float needles and seats that the float needles sit in. still gas in oil.
- rebuilt petcocks and replaced fuel line. still gas in oil.
- changed out tank for a sportser tank and added manual petcock (on/off type) capped off air barbs. still gas in oil.
At this time I was doing some frame work and added 11" shocks which lowered the back end by about 3" or so. Not sure if that is relevant or not.
- completely rebuilt carbs i mean everything. also rejetted for new open pipes and air pods. still gas in oil.
- set the blasted float height so high that it barley let gas into the carbs basically making it not run. Got up the next morning gas in the oil again.
- parked it on a hill so that it was almost physically impossible for gas to run against gravity into the oil. next morning gas in the oil.
- disconnected fuel line from tank, pinch off fuel line so no air could get in. still gas in oil.
- bought new carbs from mikesxs. those 300.00 flatside carbs that come with new manifolds and pods. Replaced all fuel lines. took tank off and treated the inside for rust then resealed it with a lining kit. Rebuilt manual petcock just to be sure. At this point I was sure I had it beat. I even bought fancy $6 dollar oil from the motorcycle shop. I had also finished my chop of the bike with a new paint job. Was riding down the road and I noticed that the engine was whining a little bit and was a bit hot. pulled over and guess what GAS IN THE OIL.
OMG!

I'm not a mechanic by any means and my solution for most problems is to work harder at my job so I can afford to buy new stuff that will fix the problems. I have no problem throwing money at this thing to fix it. But I refuse to both pay a guy to fix it for me or to give up.
Please if any of you could find it in your hart to help me I would be so happy.

p.s. added pic of the bike although it isn't recent.
