Guys

Whats the best polish or technique you have come across for bringing the fork legs up to a nice finish please?

I intend to race the bike and not show it but I dont want the forks to look dull and out of place compared to the other resto parts.

many thanks

Start to take the big nicks out with a small, fine file...Then go over the hole leg with strips of 240 grit, then 400, then 000 steel wool, then 0000 steel wool...Its pretty time consuming, but you'll get a close to factory look.After that I had them clear powdercoated.eL

If the original lacquer is on the forks, before sanding remove that with Aircraft Remover. Blue can, white letters, bottom shelf in the paint section at Pep Boys.

I have good luck polishing AL after giving a wet sanding with 220# --> 320# --> 400# then just buff with some brown rouge on a buffer then followed with some mothers....this will give a mirror finish. after racing simpley clean all dirt from it and wipe it down with mothers as needed to keep the shine on it. I have had good results with a 4" buff wheel in a small benchtop drill press. I need to rebuild my forks here shortly once my bike becomes a roller again (trying to limit how torn apart it is at once) and I will give a write up on the process I use (granted I will be using a 8" buffer to do it)

Hi there,
I just did the fork legs on my '74 MT250. Here's what I did:
- I used a Dremel (rotary tool) wire brush to take off the rough stuff
- I then used 400 water paper with WD-40
- I then used 1000 water paper with WD-40
This gave me a dull finish which is all I was looking for. I guess I could finish it off with a clear coat, but I heard that it may yellow the finish.
