Forks and rear shock were stripped and rebuilt by K Tech Suspension.
Whilst apart the corroded and scratched fork tubes with lots of areas having the gold worn away were re anodised.
According to my plater the high zinc content of original alloy means rapid corrosion of the zinc will always be a risk once the anodising is damaged.
They were dipped to remove all original anodising and I set about removing the corrosion and scratches with 240 / 400 / 600 wet and dry then finishing with red and green scotchbrite.
Not having a lathe required some creativity to create the spinning of the tubes so I could consistently sand them.
It was a two person job.
I took a large socket, wrapped in masking tape so it was a little oversize and could be screwed into the threaded end of the fork tube with out stretching it.
The bottom of the fork tube was placed upon the top of a plastic vinegar bottle screwed to a wooden base on the floor to act as a steady.
Whilst vertical, with a little downward pressure this was then spun by my better half with a hand drill using a 3/8" drive in the socket whilst I wrapped my hand a round the tube and slid up an down the tube with various grades of abrasive.
It took two attempts to achieve satisfactory anodised finish as I was not heavy enough cleaning them up in the first place. Any faint hint of corrosion must be removed or anodising wont grow on it. A repeat of the above process ended up with them looking pretty close to factory finish, I'd suggest a hint darker than original. I then added a layer of acryclic laquer from a rattle can for a little more protection.
Just have to add some NOS Ohlins decals to the fork legs
The rear shock body was stripped and replated with zinc and yellow passivate.
Remote preload adjuster was a bargain courtesy of a blown BMW shock off ebay. I ended up going with a shorter spring (170mm) so I could keep the original bottom spring seat.
Original spring can be used with a different lower spring seat (an Ohlins part from the BMW shock) however this seat just touched the horizontal brace (at the front of the swing arm) closest to the engine.
Remote resevoir hose was courtesy of Pirtek (made up at one of their depots) however I had to machine the fittings first to match original collar length then zinc/yellow finish plated them.
