Re: blue smoke when engine is running on sidestand

Hi Jarek, if it leans over far enough the lowest part of the sump is no longer where the scavenge pick up is, so the pump will stop returning the oil until the level in the sump is higher than it should be, effectively wet sumping. Putting bike on the rear stand when running should clear it.
Cheers, Mick.
