I still have wet sumping after the bike sits for a few weeks. It probably sat 3 weeks before starting it this time and it puked over a quart. This was the longest it has not been cranked since the oil pump install.
You probably recollect, this is the one I got an oil pump from VT-Cycles in Findland for. As far as the pump operation there is no problem. I know the check valve in the pump is the major factor for this. In looking at the design of the engine I think it can also leak oil throught the cam bushing into the gearcase. Is this a possibility or am I off my rocker?
