    Hello all,
    Yesterday I unscrewed the oil cap and I found a white cream type build up on the inside of cap and a water bubble??
    I cleaned the cap real good I’ll check it today?
    Any ideas?

    If your not running a stiock airbox then moisture may be entering through the crankcase vent or your bike has been parked a long time and just condensation from wet climate

    I wouldn't ride with contaminated oil. Change it first.

    It won't hurt to use the MM oil. If you have freshly changed oil a good long run at operating temperature should clear it out.
