So its burning some oil but so far not that I noticed on the dip stick, maybe not too bad yet.

But I want to tackle it, any common causes for these bikes? I am thinking being an air cooled motor worn rings are probably the cause. I can run a compression check, but just looking to hear from others who may have had the same issue.

you tear it down that far, just as well service the head too..new valve seals, lap the valves after checking them for replacement etc..just typical top end service..good luck
