Interesting issue. Have a catch-can with separate filter for my crankcase breather set up on my XB12. Noticed a spot under the filter about 30 minutes after parking it today after work. Drained my catch-can and it was almost all gas? Bike has not been running strange at all. Running modded exhaust and intake with standard race map. Any suggestions? | ||

I suggest you pop off the oil cap and take a sniff. You shouldn't smell gas in there. I know these bikes aren't carbed but my dad told me a war story from when he worked on cars in the 70's: An old guy drove his land whale into the shop for some detailing+maintenance. When the oil plug was pulled for the oil change, about 8 quarts of runny crap came out reeking of gas. The choke was stuck. The old guy drove it 1 mile every day or something. It didn't foul the plugs but all that gas ended up "downstairs". Now back to this century: Perhaps your "choke" is stuck in the form of an engine temperature sensor telling the computer that the engine is cold? | ||

Doubt it as that would cause a really rich condition skewing AFV badly, run terrible, and probably foul the plugs. | ||

Maybe a bad injector leaking down after shut down into the cyl running past the rings into the crank case? | ||

First thing I did was check the oil. Level was not high, even sucked some out with a syringe, and it does not appear to be unusually contaminated. Hopefully will get to do some more troubleshooting this weekend. First time I have had this issue and interweb search turned up nothing. I have seen this happen on carbed bikes before but never on one with FI. And there has always been evidence of fuel in the oil. Will hook her up to ECMspy and free rev it and see if MLV tells me anything. (Message edited by hooliken on May 10, 2013) | ||

Are you sure its not fuel vapors mixed with the condensation,it is after all blow by from the crankcase,send an oil sample to Blackstone labs $25 you'll know then for sure whats in it. |
