Can ceramic ports be polished (Harley related)

Since it is a coating and microscopic in thickness - no. The biggest advantage besides reflecting heat is a non stick surface so no carbon buildup occurs so polishing is redundant - MO.

Yeah, I would think the polishing would need to occur prior to coating.

Looking at the photos... The ports are not coated. The chamber is.

So yes you could polish the ports but they already look excellent.

smooth is sticky
air flow is better with boundary layer turbulence

and torque likes lower flow from smaller valves
as many hp mods hurt torque at lower usable rpm

A little simplified but he's right. ^^

afterburn, what kind of temp drops are you looking at with the ceramic coating? If I want to go forced induction in the future something tells me ceramic coating is necessary on the exhaust ports and header.

I would think i cant be the first to think of this but have found no other information.

It's easy to mount a turbo on a Harley. I saw a few R&D turbo Harleys in the 80s from Mr. Turbo. I would love to ride them now, I was 10 or so. An intercooler is a must. While the coatings are a excellent addition, you are still dealing with an air cooled bike. Stop light to stop light can be controlled, temp wise with fuel injection. Having a balance between stop light to stop light/ garage to highway/ to garage, is difficult.

I'm not sure what the advantage is, of moving the heads front to back. Maybe I misunderstood the comment?

Pro Charger offers a nice kit. I throttled a Fat Boy with a big engine and a intercooler. It's a nice balance. Ride it like you stole it, putt around town. Get into boost, it's loud!!! The blower wine is a nice touch.

I will likely go with a supercharger, driven off the crank on the left side since the exhaust is on the right side and it gets warm. Plumb it up to the intakes with an intercooler then run bigger injectors with an intercooler. Not sure what else is involved, but it's an equation I can solve in the future. My goal would be 120/120 at the rear wheel. Right now it's 100/100 at the flywheel.
