Hello to All,
I’m curious about the metallurgy of 1972 R60/5 as regards the cylinders. If new rings are indicated by a leak down test, is it possible to just replace the rings or is cylinder honing required? About 56,000 miles on the motor. I have read someplace that that particular author claimed honing wasn’t necessary on airheads of that vintage.
However, I like to hear from you experts. If honing is required, do you have any recommendations? Thank you!
