Oh. If I ever get the chance to paint my engine, I'm going for color. The only thing I don't like about my bike is the engine paint. It's this crummy al paint and I find it looks horrible.

I think you confused my other thread with this one. I do not want to paint my engine with reflective paint and especially not glow in the dark paint.

Not quite on topic as it's related to blasting, not painting, but has anyone tried vapour blasting? Some info from the DDK crowd here...

Doug, the subject of engine painting has been discussed here before. I planned to do it too but there were a lot of feedback about gas ruining the painting after spills. Having to decide between a good-looking engine with gas marks, or a dull (but clean) engine with no marks, a chose the latter.

It looks as if Andy was too modest to put a link up to his great website. Scroll half way down page one and read all about how to paint an engine.

Yea....I am having doubts how well the paint will last.....I am going to have my frame powdercoated this week and then will be putting everything back together.....right now the paint is not cured and will rub off fairly easily.   I just hope I can get everything together and the engine running without the paint getting ruined.  At that point hopefully the engine heat will cure the paint......a lot of IFs though   :(

I redid the lower cases on my 750. I left the barrels bare for contrast. Enamel paint is far more gas resitant. When I ran the bike, you could smell the paint curing for a few rides short rides.  I had a leaky carb pool some gas next to the starter and it stayed there for a few days.
I wiped it up with no apparent effect on the paint. I have noticed after one riding season the paint is not as silvery and looks more natural.

Hi, do you remember the make/colour of enamel. Sounds like good stuff.

Phil, it was simple Krylon Hi temp Aluminum paint. But is was Enamel which i was told resists fuel better than a lacquer or polyurethane. They key may be allowing the paint to cure before applying heat. There may be different chemicals outgassing and leaving just the binder and metal powder.

My only problem with powder coat is touching it up of scratched or chipped. If you have to repair it with paint, why not just use paint?

A lot of the studs came out when I was removing the exhaust system, one broke and had to be drilled out, the ones in the photo would not come out so I let them be.

Sorry about that, wrong studs, the head came off to remove a broken exhaust stud and remove a broken cam cover bolt, to save any further damage (or things getting lost)  I removed as much as possible from the head, dowels, studs etc, those did not want to move so I left them alone.

Mental note to Raul: If spitfire's invite me to come over to dinner, DECLINE.


Hey everybody, if you got a shop to work on your bikes, how about buying a scrap oven for these things? I don't have a shop, but if I had, I wouldn't even have to buy it; you can find them quite easily laying besides garbage buckets waiting to be thrown away. "Normal" people wouldn't buy a second hand oven for its intended purpose, so they are just thrown away. And not even because they are broken; simply because somebody is refurnishing the kitchen or buying a newer one.

I'm with you there Raul...if I had a bigger shop I'd definitely have one. Can do double-duty as a powdercoating oven too.  ;D

Great looking engine nippon, was going to upload a photo of my finished engine but the gremlins are still here, so cannot upload pics.
Don't worry Raul the smells gone and my wifes a great cook, she even studied Spanish at college, so you will feel right at home ! I struggle with English though.

the duplicolor 1200 degree hi-temp paint is bright silver like that. it's the 500 degree that looks more like the stock silver. mine stuck really well, but then the hi-temp clear that i used over it browned.  :-\ i reapplied with the 1200, and it didn't adhere anywhere near as well, and ended up bleeding everywhere.

here it was before it browned:

Got frame back from powder coating yesterday....looks great.   Just finished putting the engine back in.  Managed to do it by myself.  Was actually a lot easier than I expected.......here are a few pics of the method I used.













What is the best next step for assembly?   Frong forks, swingarm, or wiring harness??

Thx,
Doug
