My experience with big singles is they all use oil when spun up. Big lung creates more crank case pressure at higher RPMs which makes the rings and valve seals job harder. The whole reason I got a XRR was because it was built to last with a relaxed maintenance schedule. No "racemotor" maintenance/rebuild schedule for me.
