Sandcast GS1100E? OK this is a nonsense post just weird to see this.

[oldGSfan]

I am working on a couple of '83 GS1100E's and one has very rough castings on the passenger footrest bracket - the one on the right looks like the aluminum equivalent of stone-washed jeans. I threw a nice pair of these away not too long ago, I had to clear out so much stuff and nobody seemed to want it, so off to the smelter it went. Now of course Karma is here to taunt me. Anyway, I checked all over and they are stamped the same. it looks like someone took off early on a Friday or something. Has anyone seen ones like this?

Just the musings of a GS addict - but hey, at least there's GS content in this post!

Looks like a PO had a go at it with a coarse rotary wire brush.

For me the grain and appearance doesn't look like anything rotary or rubbing, just looks like a bad screw-up in production.

If they'd looked that bad at the factory, they wouldn't have got out the door. That's a PO's work, probably Bubba and his angle grinder trying to remove factory clear coat.

Yeah, that makes sense. I use paint stripper, that's how I did the one on the left. I am wondering if the clear they put on is gloss or satin. Probably doesn't matter.

I have recently started using sponge wet sandpapers that you can get in a pack of various grits to prep aluminum for paint or polish. Cut to fit the triangular Dremel vibrating tool and stick them on. Wow, quick work. I spray a mist of water on and wear a leather glove. All those years sanding by hand, jeez.

were these coated in thick black paint? Suzuki had a sneaky habit of using cast parts that would not meet muster for clear coat for black painted.
I polished off a black engine case once and it was nasty pitted and crude.

Not that I know of. Interesting!

It also might have had a bad chrome job removed with a coarse wire wheel.
