Nope it won't. I powdercoated a head and cylinder and rode it for 6 months before I sold the bike. Never had a problem, except it's a bitch to keep clean.Broken said:I believe the powder coating will just melt, since it is a plastic base. You would to use a high heat resistant paint to paint them. There are several different automotive hi-temp paints. You may want to look into different coatings like a jet hot coating however make sure what ever coating you get does not trap the heat on the engine.
