    Has anyone had pistons coated? There are moly coatings for the skirt and ceramic for the dome. A guy not far from me does it. I need to put a new piston in my 02 cr and the barrel is currently out to be re coated I'm wondering about having this done.... not so much for performance, more for reliability. Any thoughts?

    It really deopends on how the coatings are applied. If the moly is simply sprayed on the baked I would say no stay away from that because they moly will tend to come off and deposit itself on the bore and keep the rings from seating properly. If the moly is plasma sprayed or gas vapor deposited then it's not a bad idea.
    If you're not looking for the performance gain you might as well stay away from the ceramic coating on the tops because it does nothing for increased durability and has a possibility of flakeing off and scoreing the cylinder. That would usually only happen if you encounter some preignition (which the ceramic helps avoid) but it's one more thing to go wrong.

    Thanks:
    I will forego the coatings on the piston.
    I talked to eric today, the nikosil was fine in the cylinder, he honed it for me to clean it up and it is now on its way home.... seems like great service. Can't wait to fire it up again:applause::applause:

    hey Chef,

    What is the name of that company that does the coatings?

    Is it Swain?

    There are several big bore guys on the KTM forum running the Swain coatings and having good results.
