Ian,

I don't have any experience with alternatives to new piston/cylinder
sets, but I have had to make the decision a couple of times before. If
you don't have a good set of pistons, I don't see how you can beat buying
the new sets. I got to believe that it will cost you more to buy new
pistons and re-sleeve. Even though I don't have any personal experience,
I have heard some horror stories about the reliability of sleeved
cylinders. I'll bet there are some guys on the list who might have had a
good experience though. I was thinking about maybe using somebody like
Bore Tech to replate the cylinders. I just checked their website and they
say prices start at $195.00 (per cylinder?) for replating in chrome or
nikasil.

The last I checked, you could buy new piston/cylinder sets from MG Cycle
for $550.00 . These are Gilardoni sets with Nigulsil plated bores. They
should hold up better than the originals. Expensive, but I don't know of
a better option. I have ordered sets from Agostini's in Mandello too.
They are usually even less expensive, but with the current exchange rate,
I doubt whether they are cheaper than MG.

My 2 cents.

Hi All,

I know that most of the answers to my following question will be to
get new
cylinders but I am exploring other options. Here they are.

I am rebuilding my Police Eldo and I have a set of cylinders that
came with
the bike. I had them mic'd and they were about 2 thousands worn. The
pistons
were shot. I was thinking that I might explore the option of having
the
cylinders resleeved and install new pistons and rings. Anyone ever
done this
before? What about the difference in cost? Part of me says to just
take out
a loan and get a new set but the other sees re-using the cylinders
as
something that is good.

As always I am seeking the advice of th wise, experienced and
knowledgeable.

Thanks for the advice in advance...Ian
