1972 OIF A65

My basket case is coming on. I have found the clocks, which show 43,000. The barrels are now off and the piston rings are a bit loose on the standard pistons. What did surprise me, there is only the slightest ridge on the top of the barrels. My friend who builds engines had a look and is of the theory that new rings will do the job. I am quite happy just to put a new set of standard pistons in. Do these barrels last this long with regular servicing. ( or is the speedo from another bike )  Observations please.

glaze bust the bores, new rings reuse old pistons.

my practice is to reuse original stuff where ever possible.

If a thing is 50 years old, and only half worn, it follows that it will last much longer than you'll use it in another 50 years.
Replacement spares are often crap and very expensive.

I just bought a handful of small parts for my brothers TR6, screws, a gasket, set of clutch rubbers and so on... 50 quid,

Sounds a wise move. Many thanks.
