The metal shields on the bearings will keep heavy grease in but aren't oil tight. There was a talk about this long ago concerning cam bearings with Dale, and if I am remembering correctly the extra oil was at the risk of allowing swarf into the bearing if the engine suffered any other failure. Don't remember the verdict, maybe do a search on similar subject. 05 and up engines have a jet that sprays the bearing and I think the inner shield is now off. Don't know if the factory Husaberg site still has the 05 intro literature listed, but that info was on there. Would get some splash from the crank with the inner shield off and less likely to see swarf than on the clutch side, but is shielded from direct oil splash by balancer drive gear. Good question.
