I recall reading about a company that will coat pistons and cylinder walls, but I do not recall where I read it. When one of my flatheads need a larger size piston, I would consider coating the old piston and truing the cylinder instead of boring and installing oversized pistons.

Has anyone on the forum had experience with doing this?

Can anyone recommend a good person to do this work?

12 or 15 years ago we had some pistons coated with moly-phos, is this what you are refering too? If I remember right the build up was only a thou or two. it was to provide cooler break-in and improved service life. didn't see enough extra life to make it worth while. Don't think it was ever meant to substitute for boring over size or re-sleeving.

Dear Coolbreeze;

First you will get no shortage of opinions and preferences on this topic. These coatings were all available in years past and were tested predominately by racers. Earlier coatings had occurances of not adhering to surfaces so you will find mechanics and restoration professionals who are less than excited with aftermarket coatings.

A year ago I had my original paint 59 DuoGlide rebuilt mechanically front to back by Mike Javernik, Canon City Colorado. I chose Mike to handle the rebuild for two reasons. #1 - I have ridden with him over the years and he consistantly has top running motors. #2 -Mike rides to most AMCA events from Colorado on his Flatheads, Knucks and Pans. It's tough to keep up with him. His machines run dependably 70+ mph all day long.

Mike teflon coated my piston sides, ceramic coated the piston tops and heads inside the combustion chamber, flowed and polished my heads etc.... My 59 Pan runs very quiet, heat is dissipated faster, thus a cooler running motor. My Panhead will run along side my 95 Road King all day long now. These old motors will perform if they can breath and exhale better than original. Old iron can benefit from modern technology especially if the workmanship is done meticulously. Give Mike a call and make your own decision. You may reach him at:

For those of you who perform your own rebuilds, Mike and his guys are very well respected for their head work. Got some heads with serious issues...send them to Mike for rebuild.
