Started work on the front fork.

Some serious scratches here.
Started with 180 sandpaper to 400, 800 and 1200wet plus a light polish with a microfiber cloth and ambassador creme.
Cheers, Uli (Leonberg, Germany)

Thanks Pete.
Waiting for the clear coat to come to finish that.

Today, been to a good old friend with the brake rotor. Dated 5 14 and still in good condition but has some corrugations and marks. I assume from brake fluid.

Thomas has a nice company with CNC turning machines and luckily still an old machine perfect to work on the rotor.

Sandpaper and scotch did it.

Cleaned the hubs. Casting date of rear hub is May, 6.
Took off the clear coat with formic acid.
Slightly polished them.

Waiting for the re - zinced spokes and re-chromed rims.

Uli
Cam cradle x 1 has end cuts. Is the rocker cover original. I think the cylinders are from a later bike also.

Kerry,

I´m afraid my English is not good enough. Can you precise what you see or, better, mark that on the pics?

Can take more detail pics on Friday, I´m out for some days.

Thanks,
Uli

Yes, agree with KP for cylinders that are diecast, K2 very later >> maybe even again later?
