Used duplicolor high temp aluminum. Turned out a little more silverey than I would have preferred but I am ok with that. On the plus side I really like how easy it went on. Very smooth and no running.

Some pics........

Next time try Duplicolor's cast coat aluminum color. I just did my CM400E engine. I will post a pic as soon as I can get one.

Looks great. Won't look as silvery after it's in the frame.

Dang! That looks SOOOOOOO nice! Like jewelery! Nice job. Let us know if it holds up OK?

Doug,

If that is Dupli-Color # DH1606, It will dull-out and look more natural after a few months of use.

THAT certainly IS one GOOD LOOKING Job!!!!!!

Is mine next on the list?

Can't wait too see it in the bike AND how it holds up. Even if it dulls out some, like Mike
said, it still should be quite a sight to behold. Great Job!

Later on, Bill

Thx Guys

Will let you know how it holds up.

I am sure someone has done something similar but for what it's worth I bought 2 4-packs of rubber 7/8in chair leg caps at wally world. The fit nice and tight in the exhaust ports and the intake openings.

very nice,I hope mine turns out half as good!

...I used the same on my motor, and while I was pleased with the initial results, I was not some pleased with the way it held up. Douge, when you rub your finger acrose the motor, is there silver residue on u'r finger? Thats the way mine was, like it never really cured. If you look on the can it mentions baking parts for 2 hours at 400 degrees or someting like that. Anyway by the time I handled the motor getting it in the the bike I had plenty of smudge marks. And the first time my carbs leaked, the finish was gone in those spots too. Good luck with it, and let us know if u'r experience was like mine...

doug_id · « **Reply #10 on:** November 13, 2006, 07:45:17 AM »

oh man that doesn't sound good! Yes, I rubbed my finger on it just now and I do have a silver residue. It has only been about 12 hrs though....maybe it will cure more. Wondering what would happen if I painted over it with a different paint?

SD750F · « **Reply #11 on:** November 13, 2006, 07:52:57 AM »

Looks really good! But I want to try something different so I am looking for feedback. I am tearing down and rebuilding my 1978 CB750F this winter including the engine. You know replacing bad seal and gaskets, cleaning out the oil pan and pump with 30,000 miles on it. Checking all the valves and such. Okay the black is going away. I know not factory but I plan to do a custom on the whole bike. I want to bead blast the entire engine except for the covers which will be polished. My exhast fins will be ceramic high temp black. and my carbs will be black. So what would anyone reconmend? Has anyone done the bead blast before? And what do you think?

Awaiting replys

Lumbee · « **Reply #12 on:** November 13, 2006, 07:53:06 AM »

...yep, sounds like mine. i think that paint requires being baked to cure/dry properly. i think u'r better to just stay with what you have instead of trying to spray on top of it. i would be really careful getting it back into the bike. no oily gloves or anything. get the motor running and let it get nice and hot, and that will help cure it. either that, or will u'r wife mind a motor in the oven

bill440cars · « **Reply #13 on:** November 13, 2006, 08:33:18 AM »

What about those 500 watt halogen work lights? They put out some pretty good heat. Would that possibly work? Of course, you'd have to move them around every so often. I don't know, might be worth a shot. Just a thought, hate to see that beautiful finish messed up. LOL

I have glass bead blasted the engine on my CB350RR project bike.

Make sure its blasted with glass and not sand, the glass will give the alumium a slight sheen(gloss)....the sand will leave a very dull finish. I tore the entire motor down and split the cases......make sure you get all the glass bead out of the oil passages.....it get in everywhere.

As for up keep.....just keep a fresh coating of WD-40 on it and it will be good.

Hey Greg, That sounds like a cool idea and your engine looks nice too.

I am going to see what I can do to put some heat on the engine it before I put it back in the bike. Maybe one of those big propane powered shop heaters up close might do the trick?

gpdesign · « **Reply #17 on:** November 13, 2006, 01:58:26 PM »

A propane shop heater should do the trick. I have a 3 burner "Mr. Heater" that I use for powdercoating, it easily gets to 400 degrees. I seem to remember that someone on a powdercoating forum ran into problems heating an entire engine though somehow damaging it, you might want to look into it (caswell plating powdercoating forum).

yea......don't think I will try to get it that hot.....maybe if I can get it to 200 or so a section at a time that would help. Funny I went to the duplicolor web page and looked at all the info on the engine paint and no mention of any special process to cure the paint.

It has been less than 24 hrs since I put the paint on. They did mention that it cures for almost a week.

Bead blasting plan...

Parts wash all items. Mask with blasting mask and protect all parts I do not want to touch. Bead blast with new glass beads. Then remove mask and re-wash in a parts washer again... The the fun part, re-assemble. I will take pictures of the process.

Thanks

I just put rubber stoppers in intake and exhaust holes and taped off the rest......was easier than I thought it would be.

I don't understand why you would want to paint an aluminum engine with aluminum paint! What's the point?

Well, I think it looks newer and less grungy.....see how long it lasts. I beleive they come painted from the factory?
