I think it was the K1. At least some of them where painted. Next after that was the R1100RS and all the oilheads I believe.

Completely painted or just parts like the timing chain cover area and starter cover?

I was thinking of the boxers only. So the 1100 bikes were the first ones with painted cases, cylinders, heads, etc?

They sure stay nice looking longer than the cast finish of our airheads.

That's a far less porous cast than our bikes, that's more likely the reason. Paint, of course, helps fill in the rest of the imperfections and smooth out the surface, preventing most stuff from sticking in pores.

I don't think our cases are any more porous than the others. I think bare metal looks better a LOT longer than black. Powder coated silver like the oilheads? Man I could see the powder coat job F'ing a lot of stuff up but I am not a fan of powder coating. I like Powder coated wheels and whatnots but . . . .

I ride a '93 R100R, converted to a DS bike, on backroads a lot. The whole bike gets treated with Protect All. Mud, bugs, and beer wash right off. FWIW.

Many of the painted 1150 and 1200 bikes have a real problem with the powder coat lifting, sometimes B4 the gtee period has run out. Tinted timing chests and starter covers started from 1981.

There's a right way and a wrong way I believe...

The wrong way would be to spray paint on.

The correct way is to carefully rub it on. The method involves rattle can aluminium paint and a rag or two. Clean it all up first. Then spray the paint in small amounts onto the rag, NOT the case, and rub it in. This helps force the paint into the small crevices and imperfections that are impossible to see, thereby smoothing the surface some.

Have you thought of Rub 'n Buff? Do a search in here somewhere. It's a wax/polish compound that also does an amazing job.

This guy was at the Olds Cool spring meet up, he was not with the group, he did not know what ADVrider was, he painted the engine and damn it looked good.
From what i gathered from him he was schooled on paint work, he mentioned you have to do a conversion process (whatever that means) on aluminum engines in order to make the paint stay long term, his work spoke for itself.

I stole this pic from RedBud, i hope he doesnt mind.
click on the silver airhead pic and you can choose the size of the pic in the upper LH corner.

I'm inclined to go with silver paint. I just don't like the look of oxidized aluminum castings. Need to figure out what process to use...

Raw metal looks cool, runs cool, is cool

I'll go against the grain and say -
The raw metal looks better than any coating and is easier to maintain.
Filling the pores of the casting with a coating reduces the surface area and the cooling effect.
