Just wanted to pass on some good information for those who run into a problem finding
oversize pistons for vintage snowmobile engines.
There will be times that oversize pistons aren't available for the engine your trying to
rebuild. Only standard pistons are available, but your cylinder bore is wore beyond the
stock cylinder clearance spec!!!
The Kinkacil process used in the newer style engines can be done to the older style
steel sleeved or cast steel cylinders. This is a plating process and can be done up to
.040, honed and brought back to standard specs. This is cheaper than re-sleeving and
is a better set up.
It's called Nickel Silicon Carbide (NSC) and can be done by:
