green forks
« on: June 07, 2009, 07:16:58 AM »
picked up the bike this weekend, started to clean it down was looking at the forks they have a green rust above the fork seal can these be polished and greased?
 they will have the rubber boots put back that where missing so they won't be seen.or do they need replacing?the motor was froze, so a little marvels and a forthgear bump freed it up and the frame cleaned up like new, but alot of work ahead.
thanks

Let me guess, aftermarket chromed forks. The plating has wore off, down to the copper. Copper turns green when it corrodes..

Clean em up and run it. dont use anything abrasive.

If a rough area will go through the seal when the fork moves, the fork is no good. If it stays above the seal, just clean it up.

 i don't know about the forks being copper underneath they were there when i got the bike.that being said i hit the forks with 300 than 600 paper then some neverdull they polished up pretty well ,there's no discoloration to them so i'll spray them with some silicon spray and hope for the best .worst case i have to replace them.
pictures i'm working on.
thanks for the replies

yes it looks like the chrome is still there. this whole bike has this greenish white oxidize  powder on all the chrome.it's even on the aluminum but that polishing up nice.

Well, sanding them probably killed them, unless they  corroded with zits on them..

 Chome fork, ie aftermarket are first chromed with copper, then nickel, then chrome.. I dont know of many metals that turn green, cept copper..

Ditto. All I have to say is you hosed your forks doing that. If I were to ever use paper on my forks, you'd better believed it would be a 1500 grit or higher wet sand.
