I have a 1998 S1 that just started puking oil/gas from the hose at the back of the engine that goes over the battery. This is alarming. I haven't been able to find any good info. Things range from "crank seal is bad" to "engine cases are cracked". I ran it for a few minutes and it quickly spits it out. I let it spit into an empty water bottle and it has a strong smell of gas and is very thin. Any ideas? | ||

Be patient someonevwith info will reply. Note what color any foam, what type of oil when was it changed all questions they will ask Sorry I dont have info but many have gone through it Try google buell oil and gas out of tranny vent you will get hits | ||

Ok so a little quick research and your simplest issue it could be and lets hope is your float is stuck on your catb dumping to much fuel causing it to run into the rngine thinning the gas and thus allowing it to seap past the seals. To check first always make sure you turn the petcock off when not riding. Pull carb inspect float if its stuck fix then Drain all oil and gas refill both tranny and oil use cheap stuff let it sit for a couple hours the gas has cleaned the lube off all the bearings. Run it for five minutes then drain and repeat. Then drain and add good oil . Otherwise crank seal have heard its not to bad to do if you pm buellistic he can send you detailed instructions | ||

Thanks. Great info. Changing oils now, and checking float. Hoping thats the problem. I used to close the petcock every time i parked a bike. Not sure why i quit, but it is now a must do every time... | ||

Float might be perforated, or the diaphragm to the accelerator pump might be leaking. Gas in the oil usually does not happen while the engine is running. I had a fuel pump diaphragm fail in my microbus and hydro-lock the motor with gas. Gravity feed can be a bitch. More than a quart of liquid gasoline came blasting out of the exhaust when I pulled the plugs and turned it over. Fuel shut-off valves are beautiful things. Your float needle is the first place to look. Buellistic's RIP thread is on the quick board. | ||

Float and primary seal get my vote. | ||

Not to mess with this post but the buellistic news is very disturbing I would get a call from him about 1 time a month this summer I had kids getting married and graduating time flew by. I am very sad | ||

yeah. it's weird in here without him. | ||

Kinda off topic but my snowmobile brand new sitting in the garage with a full tank dumped all the gas out. They said the ethonal ate right through the seat! Everything gets shut off unless its injected at my house | ||

Flooding can dilute the engine oil to the point where the crank seal no longer can contain it (when running). If the flooding is severe, it can fill the flywheel cavity (when parked) to the point where it bleeds past the crank seal. Either situation can overfill/dilute the trans fluid so it blows out the trans vent line. It's possible that the crank seal is still good - it just couldn't retain the gas-diluted engine oil. | ||

Another symptom is that the thin oil-gas mixture will fill the primary case and begin bleeding out of the clutch cable up at the handlebar end. | ||

my s1 and x1 did the same till i replaced the crank seal using the double lipped revised crank case oil seal part # 35151-74A | ||

It has been remedied. Took the carb off, cleaned it and adjusted the float. I flushed the engine and trans with cheap conventional oil two times, replaced the oil filter and filled back with the good stuff. Hasn't leaked by the seal yet, so thankfully the seal is still good. Gonna put a sign on my garage door into the house "Turn the fuel off!" and then a sticker on the bike "Turn the fuel on, Dummy!" | ||

The new oil seal is not that hard to install and is a significant improvement over the single-lip design. You can see if you have the new one by simply removing the primary drive sprocket (and primary chain, and clutch basket) and looking near the drive shaft to see if the visible portion of the seal is metal (old) or hard plastic (new). Remember the clutch basket nut is left-hand-thread. Drill holes in the old seal's metal ring and use self-tapping screws to pull it out. Grease the drill bit to catch the shavings. |
