Black Engine Paint

[sebring38]

when i bought my 82 GS850G the engine was painted black. It does not look very good. First question, did any of these bikes come from the factory with black engines? If I wanted to remove all of the black paint, what is the best way to do that job in my garage (without a sand blaster)?

I know they didn't come black - as for how to remove it...I dunno - good luck though!

I think my 83 650L did come with a black engine.it still looks brand new, take a look.

Sure does look good. Wonder if paint remover from Home Depot would be ok to use on aluminum?

I don't think any 850's were black. If you want to remove it, use aircraft stripper which you can get at automotive paint supply stores. It will take off paint and clear coat, but doesn't seem to stain or etch the aluminum. But make sure you only get it on what you want to strip.... stong stuff!!

Its all original. Still has the clear coat on it and original paint.

aircraft stripper will work well can buy in rattle cans from Wal-Mart also

this leads into another direction, but I powdercoated my cylinders and rockerbox covers (obvously not my gs) and its awsome. So if you decide to keep it black, thats the way to go.

Powdercoating engine parts looks good, but is not reccomended for air cooled engine cylinders. It's too thick and can increase heat retention. Even an epoxy based paint can increase heat retention.

What did they paint the engines with at the factory.I think mine is original black

Mine is too. I've been told the factory paint is an acrylic. Epoxy and especially powder coatings are very thick. The trick is to strip the old paint off instead of layering it on. I'd bet the additional heat from a thicker paint is minimal, but I have heard that performance engine builders avoid it on cylinders.

I disagree, although i thought the same thing before i did it. The heat retention of powdercoat is comparable, if not better to that of most other coatings and the lifespan and chemical resistance by far outweights any con.

Most new air cooled bikes come from the factory with powdercoated cylinders and heads. I actually had to uncoat mine (was an aluminum color) before doing them in black.

Now, if its not done right and is way to thick, then yes it can cause problems but not if dont correctly which any reputable shop can do.

I thought that the factory started painting engines black in 83 to help get rid[\i] of heat. I have an aluminum 650...wanna trade that black 850 for it?

I know that in 1983 that the GS750T's were produced with black engines.So I would say that the 1982 & 1983 various models were produced with the black engines too.:shock:

hi

tracy that would have to be one of the nicest bikes i have seen on here.

congrats on a wicked bike.

sorry for hijacking the thread

cheers

 

[Jethro]

Oh yes, definitely the best looking "T" I have ever seen.

 

[tracy borchert]

thanks

thanks

Thanks ramjet and Jethro, I put alot of work into her last August for my birthday.:-D
