Restoring Engine Shine

Yo,

I am trying to restore the luster of my CB360's engine, which is now a dull grey. I don't want to remove the engine and strip it piece by piece for polishing. Is there some method to do this by just throwing some elbow grease at it with the engine still on the bike? In preparation for starting this task this weekend, I purchased the following: Green Scotch-brite pads, very fine steel wool pads, and oven cleaner. What do u all suggest?

Yeah I figured the steel wool would be bad. I will go at it with the scotchbrite and maybe try out the oven cleaner. A fun weekend of scrubbing! On other forums I see guys taking the engine apart, dremeling the pieces, and polishing them on a buffer wheel. Unfortunately I do not have the time, expertise, tools, or the room to do that!

ummm before you try oven cleaner read the lable, some are not compatible with aluminum and will etch the crap out of it,

engine type cleaning i prefer a product called foamy engine brite, its sold at most every auto parts store and is pretty cheap as well. it doesnt harm paint or rubber in my experience adn rinses away with water

I would suggest removing the factory clear coat then sand and buff.

If you sand lighty and in on direction after an aplication of paint stipper you'll be very satisfied with an even texture for more shin buff .

I prefure the sanded and the fresh clear.

Man it's alot of work but you'll never get an even finish if theres any factory clear left on that piece.

Haha yeah don't worry I will read the label. I am actually not expecting a mirror shine at the end, I just want a decent color at the end of my efforts. The engine at the moment is a dull grey with a sort of very light tan buildup, and old oil/fuel grime on the heat transfer fins. If I get rid of that I will be happy. Anyway a true cafe racer should have mismatched parts, be leaky, smelly, and just be able to do the ton without winning any beauty contests no? :-)

The light tan build up may be the clear coat I mentioned.

use an engine cleaner rather than oven cleaner it will work far far better plus not ruin things

Yeah oven cleaner is outta the picture. I started going at the engine with the scotch brite pads. After putting in 2 hours and getting my hands all green/grey I got some shine.....in 10% of the engine surface area.... I think I may just go get a dremel tool and see what happens.

Ok so I attached the scotch brite pads to a disk mount on a power drill and it gets the job done sooo much easier. My other forum suggests that using Autozone carb cleaner will remove the varnish easily.
