He put JB Weld on it but as soon as I put gas in the bike they softened up and fell off. What's a good alternative for repair? I tried to solder them And...

Has anybody upgraded the springs in the standard 43mm forks, I tried to get some progressive springs from Hagon shocks but they don't make any. I was just wondering if anybody had done anything similar? Cheers Andy

Couldn't find anything on my problem, I'm sure it's an easy fix but it would be a bit easier if I new where to start.
