recoat or sleeve, what better?

like it says, whats the best way to go? both are about 200 but you have to pay for machine work for the sleeve.

have at it.

do you mean replate? i would never sleeve something that can be plated. plating is far superior, assuming is done right and isnt electrofusion.

Replating is superior.

Sleeving a plated cylinder is like painting a Corvette with a spray can. Sure, it will work, but it ain't the best way...

another vote for plating

If Kawasaki thought it was a good idea to switch back in 1979, then no need to go back to 1978.

thats great guys, why is plating better though?

lasts longer than a sleeve, as it relates to wear

runs cooler

it is a much harder surface than any type of plain old metal, it wears better, transfers heat better. you also dont lose a bunch of material like you would when machining a sleeve into a new cylinder. in theory it has better oil retention, and less friction than steel or iron. also because it is so thin, it wont have a tndency to "pull away" from the cylinder, or become lose from contant disimilar expansion and contraction of disimilar materials. i hope that made sense

All true. Also:

Since the plating expands and contracts at the same rate as the cylinder casting, the bore is more dimensionally stable.

The piston-to-cylinder clearance can be tighter than with a sleeve. An aluminum piston expands more than a steel sleeve, so the clearances have to be greater for a sleeve. With a plated cylinder, the piston and cylinder both expand at the same rate and by the same amount, so the clearances can be tighter, making a quieter, longer lasting, and better performing engine.
