Question for any mechanics
Recently changed my pressure regulator because I was running rich (I thought it was busted). The problem got worse. I openned the airbox to see oil on the bottom. My oil level is now far higher than it was before. Is there any way that fuel and oil can get crossed and fuel can leak into the engine oil?...or oil into the air box?
I'm getting nothing but smoke out of my pipe and when it idles, RPM's drop and it kills.
Any ideas?

I am by no meens a mechanic but it sounds to me like you have some bad piston rings causing pressure drop. as for oil in the airbox, i'm not to sure. I hope someone other then me can help you out. g'luck.

RE: Question for any mechanics
Thanks.
I found the problem.
In case anyone cares, here's my theory.
I had a bad fuel pressure regulator that's been getting worse for the past 4 months. I've been working on it and starting and stopping the bike without taking it on the road (so I never checked the oil level). The fuel pump was pumping fuel right past the cylinders (#1 and #4) without a regulator to slow it down. There wasn't enough air for combustion while it idled, so the fuel went straight past the cylinder and seeped into the engine oil.
When I finally changed the regulator, I noticed my oil level was high - really high. About 1 gallon of fuel got into the engine oil. After I changed the fuel regulator, the oil and filter, the bike ran like the day I bought it. Took me 4 months, but the problem is solved.
Thanks again for the help.

I'd want the fresh oil to circulate, mix with the (little bit) of remaining old oil and flush it again.
I would definatly do this to be nice to my bearings at 10,000+rpms.

Buy the cheapest oil and do about 3 to 4 oil changes. Put the oil in and start the bike for a few min and dump. Same thing again. Like 1000rr said.. gas and oil are not friends. You can burn the rings up quick with gas in the oil. Good Luck!!

RE: Question for any mechanics
same thing happened to my katana, except it had been sitting for a year, and a bad float needle, or similar, drained the entire fuel tank into the crankcase, I had it run about 10 seconds before I noticed this, shut it donw, drained the oil out twice
