Gun-Kote on cylinder/jugs

[gsryder]

Has anyone used the Gun-Kote paint on their cylinders?
My concern is that when I bake the paint at 325 for an hour I may take a chance of breaking the sleeves loose.
Has anyone else done this or had any experience with this?

Would it need a hone or even a bore after being exposed to that much heat for an hour.
I have a good motor with a low mileage rebuild (but it has been sitting for 10 years) that I was going to take apart for paint and fresh gaskets/seals so I was not planning on reboring it.

Any thoughts would be appreciated.

I'm thinking of using some too. Good questions.

325F might well loosen the sleeves but once it cools down they will tighten up. Worst case I think you could take a block of wood and bang them back down if they lift while cooling. Not sure about rusting in the bore while baking. I think it would be a good idea to paint first and hone second.

it's best to call them, (gun kote) they have a guy there that has done some Kz's so he should know what to expect.

I've done that. Sleeves slid up, or the block slid down, how ever you want to describe it. Just pushed them back into place and let it cool. No harm done....This time.
To do it again I would turn the block upside down on a steel plate to keep everything in place. Might want to think about replacing the barrel O-rings at the base of each cylinder while your at it.

Interesting madjack did you hone the cylinders after that or just reassemble and run it.
My cylinders, pistons and rings have very low mileage on them so I was trying to avoid buying new rings and rehoning........but I want to do it right.

I will call the guy at gun-kote also he was very helpful when I was picking out the paint I talked to him for about a half an hour BSing about bikes and what not he has a pretty bad azz Harley.

Honed with a ball hone. Never had a problem with ring seal (was a 78 kawi Z1-r)
