Oil in left spark plug hole...

[sky1haze]

First of all, Thanks all for helping me during the last few months.

My new problem before winterizing was when I pulled my plugs, the left plug was wet with black liquid.
The bike runs great when the plugs are clean, then the black comes on and it drops out and stops...
Any suggestions?
There is no smoke coming out of the exhaust.

Joel, have you done a compression test? Could be bad rings.
