There are a bunch of places now advertising nikasil repair.
Has anybody ever had this repair done ? By whom ?
Were you happy with the result ? How much did it cost ?

For a 1000 cc airhead BMW twin, it looks like somewhere
between $350 - $450 for two cylinders stripped, repaired
as needed, plated and brought to spec.

I just stumbled into a set of cylinders and am considering
this repair.

No idea, but that sounds cheap. What airhead boxer do you have, out of
interest?

(As one who has a soft spot for them)

Rob,

I've used Millennium Technologies for snowmobile cylinders and was very
impressed with their work. It was about 4 years ago and cost a little over
$200 per cylinder. The snowmobile is still running well.

'88 R100 GS.

The current cylinders have 137,000 miles on them.
They survived a badly trashed rod bearing and got
transplanted onto a new short block, so I'd say
they've served honoraby.

Over the weekend I acquired several damaged
cylinders as part of a milk crate full of bits
and pieces. I'm thinking of sending these out
for replating while I continue to run on the old
worn set.

The bike is an '88 R100GS.

The cylinders are the originals with 137,000 miles on
them. They survived a badly trashed rod bearing at
95,000 miles and got transplanted onto a new short block,
so I'd say they've served honorably.

Over the weekend, I acquired several damaged cylinders
as part of a milk crate full of BMW bits. The plan would
be to send these out for plating while continuing to run
on the clapped out originals.
