Degrease them thoroughly and put them in a bucket of Molases mixed with water at 4:1(ie 4 water -1 molases) leave the bucket outside(it smells) for a week or more.The mixture only eats rust.
Molases can be bought cheaply at your local farm produce store.
I  use it to clean up all my rusty parts,works a treat.

WARNING Do not use on alloys or magnesium,it will dissolve them too.

the platers give a supersonic clean don't they?. I would go and buy a box of 6, 8 and 10mm nylocks and just do the bolts.

any acid will work to remove rust, just the strength is the issue. I use diluted hydrochloric acid. works really fast- be warned  if you forget the part in the acid it may be destroyed or gone!
I give a Quick wire brush and  just dip and brush until clean(couple of minutes), but the plater will also acid strip everything.

I like to acid clean before welding any old parts, getting rid of the plating stops the eye blinding flashes if tigging

There is a product called Rost Off and Rost Off ice Wurth sell it.

Rosco Holden used a product called Protec Metal Conditioner Degreaser to clean the pipes he got from the Flood collection.

Or aluminium cleaner will also do something similar

Are these forks WP or Marzocchi Forks?  Whatever they are has anyone got any settings (Oil weight spring Pre load etc.) for them?

Ok I have got a bit of a problem.  The Motoplat flywheel needs a 28 x 1.25 internal thread.  I have tried a 28 x 1 puller with no luck.  They seem to be used on the later Rotax motors like ATKs.
If by chance you have one could I borrow it :P Unless someone can lend me one it looks like I will have to get one made.

Read the digital vernier properly 27.82 would be a 28 mm thread.  A good engineering (machine) shop could make a puller for it. But at $100.00 plus an hour it won't be cheap.

Noel,

Nice new project. Strange beast... never seen one of these before.

That puller is an odd size, 27mm x 1.25 is common enough however the 28mm is scarce.

I found one here: http://bit.ly/1rl38H3



And..... another one here:

The UK might be your friend on this one.

Nice bike.

Cheers

Jock
