Saw that someone oon another post had powdercoated all of their engine parts. I have never done this thinking that the PC would locki in heat more and leade to piston seizure. But I have a buddy who does it and he says he never had a problem.

Anyone ever PC an engine or barrels only then actually ride it for a while and experience any problems?

Not 100% sure, but I think S&S powdercoats their cylinders.
Back to work, man I hate 100+ degree days.

see this thread for similar content .. I have 2 Pan motors with supposedly "aluminized" cyls, dont know if it's "real" or gloss powder; and havent run either yet ..

http://www.jockeyjournal.com/forum/showthread.php?t=6857&highlight=aluminized

I'm also looking into powdering cylinders either gloss black or stainless/grey .. havent yet gotten conclusive answers as to if hi-temp powder is needed, or even first-hand accounts of in-service life ..

i have p/c several motors for customers. never heard any problems with them, but then again they were all show bikes. it will trap in heat, it basically covers up all the pores in the aluminum. i even have coated the inside of a 45 motor to seal it up. we even had a customer have his lower end chromed, agaisnt our advice.

I have powder coated the barrels on my EVO XL and have around 4K on the engine since the coating. Not a super hi-comp deal. I used K&B pistons. No problems to report. I didn't get any special hi-temp powder, just gloss black. No performance issues and the cylinders still look great. I do live in the northwest and the ambiant temps are pretty mild here.

S&S powders their cylinders. I know a woman who "seasoned" the cylinders on her panhead. She figured that it worked on cast iron frying pans, why not her cylinders.Last time I saw the bike,about 2 months ago, they still looked good.She did that a few years ago.Not sure how often she repeats the procedure,though.

Anodizing the parts is a good option if the part is aluminum. It doesn't coat over the pores of the metal but dyes them instead.

Wes,
Here's a complete Honda 450 DOHC motor I powdercoated in the early 70s before the technology was commonly available. I had a friend that worked in the industry and we "experimented" with several applications of powder on frames, motors, wheels to reduce the "orange peel" and to test the durability. I also did the jugs on a 47 Indian Chief with no problems. I ran this particular motor hard for several years with no problems and sold it to a guy who ran it for many more.

A dude out here on the island by the name of Paul Tracy, some LI guys might have heard of him, been around forever. He chromed an entire motor, back in the early 70s I guess, he said it was the hottest fucking thing he ever rode on, looked like a jewel but he would never do it again.
