When my bike gets upside down (seat is lower then the tires), crank case oil comes out of one of the vent tubes. I do not know if it is from the Power Valve though.
Well, that's how it ended up - seat downhill.
But this is a two stroke - should only be fuel (+ 2 stroke oil) in the crank case. So anything out of the powervalve breather should be either black spooge or unburnt fuel, right?
The grey is scaring me. I killed the engine straight away, so I don't think it's indicating water. I would guess that it would have taken some time for water/coolant to mix with the fuel in the crankcase. In any case, it seemed more like tranny oil than fuel, spooge and water.
So this leaves me thinking that somehow tranny oil has made its way into the crank case, or that it has exitted from somewhere other than the powervalve breather.
I am not familiar with the structures of the crank and tranny, but I would assume that the chances of oil transferring between the two are fairly remote. But I cannot locate a crack on the underside of the tranny, so it doesn't seem to have come from there either. Maybe I've knocked the drain plug. The thread on that wasn't the best.
I haven't been able to drain the tranny or radiator yet (damn work). I'm just guessing at scenarios really. I would appreciate some comments on the transfer of oil between the two cases from those familiar with the structures.
Thanks,
Buck.
