Title: How many miles on chrome bores?
Post by: T4halo on March 02, 2019, 05:20:10 PM

I talked to a guy yesterday with a 850T3 FB with over 80k on original chrome cylinders. Anyone top this amount?  I told him he was taking a huge chance. He didn’t care.

The more regular the use the better, it's sitting around that leads to flaking.

Didn't Karl Werth (not sure I spelled his name correctly) have something like 250k miles on his T3 before the chrome bores were replaced? Thought I read that somewhere.

I put over 100K on my '70 Ambo back in the '70's.  So did a buddy of mine.  Didn't know it was a big deal.   :rolleyes:

IIRC this engine had 250,000 miles with chrome bores.

Cheesehead of MG Cycle had a loop sidecar rig with well over 100K. It was in daily service, though.

Yes this old lumps are WAY over built and way under stressed. Doomsday stuff for sure but if you get one with chrome bores they need to be dealt with sooner than later.
