engine cases *revised*

[barstool]

I think I was asking the wrong questions.

What kinds of paint or coating did Suzuki use on the engine?

I have see restorations where the outer engine cases are highly polished. How hard is it to maintain that look? Are they clear coated after polishing?

Has anyone powder coated the engine with the new ceramic high temperature coatings?

Do you think black would look good on the middle engine parts?

Thank you in advance for any help you can offer.

Suzuki used a clear laquer on the engine. It had a yellowish cast to it and it oxidized badly in very short order. It is exceptionally difficult to replicate, although I have seen some excellent jobs.

Aluminum oxidizes instantly upon contact with air. If you polish one, be prepared to spend time keeping the finish up. That said, there are some very good clear coats that last quite well now.

I have used both ceramic coat and high temp ceramic paints on bikes for years. Seevral bikes I have done had the proper and trans case painted black (centerline of the bike) They have held up quite well, but it all boils down to the prep work.

Bottom line, do what you like... It's your bike. They are only original once, if that is important to you, restore as close that you can to original. Once you start changing things, you may as well change whatever you want... Just my 2 cents.

Best,

I have a polished finish on my RE5M. The polishing was done 10 years ago and still looks fantastic. It can go 6 months in the shed with occasional rides without needing attention (except if you venture out in the rain).

I have been very surprised at how little maintenance is required on my polished alloy surfaces. I am told this is because the quality of polishing is much better than factory leaving a "smooth" surface that is less likely to hold moisture or other crap (at a microscopic level). The same low maintenance is also true of my GT and GS polsihed surfaces.

Coating them is more original but I find that eventually stone chips etc will damage the finish and the corrossion starts under the coating (just like a factory one).

If you intend riding the bike, then polishing the alloy alone works well. But obviously don't ride in the rain and let the bike sit. Wash and polish ASAP.
