Had a bit of a blast last night after work. rear hub looks fine. Not even attempted to move the retainer yet until I have made a tool for it. Is is LH thread? It is made of steel, are they supposed to be alloy?
header pipes double skinned must be originals chopped from standard pipes (you can see the spot weld in the pics). Going to strip down the electrical parts to re-plate.
Got the engine out. One lower bolt was not too stubborn but the other side I had to chop through the nut with a slitting disc/cold chisel. Not blasting the lower yoke, just going to repaint it.

Just been investigating the black finish on the carb rubber clips and the top yoke 'D' spacers. At first wondered if it was 'Japanning' ..like you get on old screws and tacks but convinced it more likely to be black passivate, which I didn't know existed but Gateros plating do it. Problem is its £24 as compared with about a tenner for the blue/gold chromate passivate. Will ask the barrel platers if they can do me a few items, may be cheaper or get Gateros to supply me 1 litre instead of 5l as unlikely to ever use it again.
Can someone confirm that the 500K0's had black finish clips originally please? The pic below is of a K2 not a K0. the other pic is of the the ones I have (after bead blasting). Going to dunk them in my 'brew' in the slow-cooker today to remove any traces of zinc, corrosion. If they are indeed zinc plated I will see loads of bubbles, when I dunk 'em.

Forks are perfect in the chromed area no pitting whatsoever. Usual corrosion around bottom yoke clamp but I can deal with that. I masked the sliders from the bead blasting with 'gaffer' tape and I will use chemical stripper to try to retain the original finish before applying new clear coat.
MY ADVICE TO ANYONE IF JAMES H IS SELLING A "PROJECT" BIKE... GET IN THERE FAST AS BOTH BIKES I GOT FROM HIM ARE SPOT ON ;D

Chrome is perfect .. seems a shame to spend 170 quid when the chrome has survived over 44 years ... having said that, I deliberated over this on my 750K0 and bought brand new Yamiya stanchions. Has anyone else used /treated Honda stanchions that have perfect chrome but corrosion near the clamp area? I don't want this bike to become a money pit like the 750K0 or remain in pieces forever (like the 750). Big determining factor is if I manage to get stock pipes with D/Skinned headers or not.
