'98 S1, rebuilt carb, runs great! unfortunately, after first ride, float was stuck, and dumping fuel out of the overflow tube. The next time I cranked it, it DUMPED fuel out of the trans. vent hose all over the back tire! Cleaned it up, added fuel, and it ran great, but started leaking what looked like transmission oil around the front of the engine. Today I removed the derby cover, and oil just POURED out! Could the breathers on the heads be blocked, creating crankcase pressure? Any suggestions? Thanks! | ||

Fuel went into engine and thinned oil so it flowed past crank seal. Drain trans and engine oil.Refill and see what gappens. | ||

What Jim said. I would even go further. On my brother's FXD, fuel seeped past the rings and into the crankcase due to a stuck float and an open petcock. We cleaned the carb to unstick the float, drained the oil/primary, filled with cheap new 20-50 oil, ran for a couple mins, then drained it, and filled and drained a second time, then put standard oil in it once we believed it was flushed and gaskets weren't leaking. | ||

Thanks for the advice! I'll get it done this week. I sure appreciate the experience and willingness to help! | ||

Same thing happened to me once on a Triumph 650 that I left the fuel petcock on. I resolved the problem using the exact procedure Phelan posted. | ||

If it continues to pump engine oil into the tranny after you change the oil, change the crank seal. | ||

A crank seal failure is pretty much guaranteed at this age on an M2, so the question isn't if the seal failed, the question is if it just failed on you, or if it failed and was replaced already by the previous owner. Not a huge deal to replace it. The only real gotcha is that the torque spec for the stator bell is too low. Don't seat the seal too deeply, and be careful getting the old one out, that aluminum in the case is as soft as butter. | ||

There are TWO TIMES you turn off the FUEL VALVE on your GAS TANK: Wale hen you turn the engine OFF and when you TRAILER your bike !!! "WHY YOU ASK ???", well when you turn the engine off and the float valve does not seat correctly and trailering the float will move up and down on bumps(rough roads)!!! | ||

Be extremely gentle is getting the gas out and clean oil into the engine - you have washed every bearing and bushing with a very strong solvent. I did the same thing once, and the bike survived it, but I watched a friend destroy a big twin Evo bottom end in the same situation.
