The story continues. Apparently my '81 R80 is more like a /7. It doesn't have Nikasil cylinders. The microfiche, based on the vin number showed that it does. The Nikasil ones I purchased looked good but the diameter of the section fitting into the block is slightly larger. Anyone have this experienc...

Hello, Not burning oil, nothing visible. And I haven't been putting enough miles on it in the last few years to notice any appreciable oil useage. I change it based on time as much as mileage.

Hello, Hoping to get some advice. Going through the top end and on my left cylinder I can see that it has lifted off a bit on a small spot. And I'm out of $$. I have about 50k on the bike but as I'm getting older I don't ride as much, maybe 2 to 3k per year. Anyone have experience with this type of ...
