Anybody have this problem in the past? Just contaminated a second batch of fresh oil and filter when I tried to start the bike. Thought the problem was a disconnected fuel line in the tank, which I fixed. It all started when the bike died on the road. WhenI got it home to try and start it the starter would turn over at first, but eventually it would not despite a charged battery. I then realized the engine was filling with gas everytime I tried to turn it over, fuel was leaking from thelower exhaust pipe and the site glass was void of any air. I opened up the drain plug and a ton of oil and gas came out. I refilled the crankcase and the motor at first turned over until I realized gas was again leaking from the lower exhaust pipe. I disconnected the fuel lines and electrical under the tank and hit the starter switch again. The motor started and ran for a few moments before depleting the fuel that was left in the lines. That told me I have spark but for some reason gas was gushing into the cylinders at a high rate, flooding the engine. I made no more attempts to start the motor out of concern doing that would damage it.
The floats in your carb are sticking, thats why your bike died while riding. You should clean your carb and reset your float to shut off when the bowl is full, by bending the tab that holds the float pin upwards. Or order a new float and pin. Reassemble change your oil again and happy riding. Don' t worry about your rings ther'e just fine.

There is no way for fuel to get passed the rings right? So if you filled the head with fuel, it would just work its way down the exhaust pipe and out the back, just like its doing. The only way of getting fuel into the sump is; if you have seriously bad rings (it would be burning oil) OR if its getting through the breather system. I don't even think if the injectors were on full-time, it still wouldn't get into the sump... very strange. Are you sure its not coolant? A serious coolant leak can be completely unnoticeable from the outside, but catastrophic to the inside. __________________
