Cleaning engine/crankcase?

[OzJavelin]

When I bought my GS550 it had been rebuilt and the engine, etc was all very clean and neat.

My GS750 is all "fuzzy" from the aluminimum oxidising. I don't want to pull it out/apart just to clean it. When should I use? Someone suggested just using a wirebrush, etc and clean it up as best I can and paint with VHT when done.

You could, but the clear coat on there will probably make it very difficult.

I went the rebuild path with my 450 though so I can't say as I've tried...

I used zip strip on my 550L and let it sit for a few minutes then hosed it off. I could see the clear coat bubble loose. When I put the hose to it, the clearcoat washed away. With some fine emery paper (1500-2000 grit) you can get the discoloration off. I used Mother's aluminum polish afterwards and it looked as good as new. Since it doesn't have a protectant on it I have to polish it up each spring. Not a big deal, it's worth the trouble.
