Rich,
I would think that as long as the bores are good they will stay that way.
Being from the "rusty" north I think that what causes the bores to flake is
that a very small hole, crack, or whatever allows moisture to get behind the
chrome and oxidation spreads behind the chrome. The pistons remove anything
that starts to come away from the walls and the process continues till the
chrome is gone. I see it on the chrome and painted surfaces on cars here
that are attacked by rust from the road salt.
If you are riding regularly, keep the oil changed I don't see why you can't
run on those cylinders for another 100,000 miles. I know a guy up here that
has over 100,000 miles on his Eldo and he parks it in the winters.
Also....I think that some cylinders were likely a little better than others.
Maybe you got one of the "Wednesday" cylinders :-)
Now if your clutch plates are original...I would be concerned.
Regards...Ian

Loopers, Took the Ambo out for a nice 50 mile loop today. Cooked dinner
| for my wife and daughter and since I was such a good cook :-) I got to go to the garage for a couple of hours. So I pulled both the |
| and exhaust manifolds, the oil line, rockers, head bolts, and pulled the heads and cylinders off the left side. So I find no wear on the rockers or pins, the heads have minimum carbon buildup, the pistons are only a little crusty on top (already scraped clean) and the cylinders look as nice as the Nikasil ones on my Cagiva. This is to say I can see no flaking, pitting or feel any ridges from wear. Sure the bore where the rings don't make contact are a bit duller than the rest but my fingernail can detect no ridge. And |
| of the O-rings fell apart as soon as I touched them (already covered as I acquired all of the gaskets and such before starting). This is on a '71 |
| with 46K, that the second owner (who owned it 17 years) reported only |
| the pushrods replaced due to one breaking, on the top end. So someone in |
| know of the vastly reported problem with the chrome bore flaking and/or wearing out please enlighten me or give me the signs I should be looking |
| How many miles do ones with good care and don't sit a long time go? She |
| not smoke except for when the choke is on and compression test runs about |
| psi with my 20 year old gauge. I feel like a happy camper but don't want to get too optimistic. Now if I only felt this good about the clutch but will report on that when I get the time to pull the tranny. Any first hand knowledge, reports, wisdom, BS or encouragement will be appreciated. Rich |
