Hey, I've got a buddy's yz450f forks apart, one of his seals was leaking and he asked if I'd fix 'em up. I took the cartridge out of one of the forks and the dampning rod would compress without any effort, and would stay compressed. My first thoughts were either a cracked free piston, or leaking cartridge/ICS seal. Knowing that the free piston hadn't been modded (holes drilled) I figured that was the most likely culprit. I pulled the base valve assembly out and below is what I saw. My question is this, is the damage pictured typical of the standard free piston damage ? I've seen pictured of KYB free pistons that look like they've imploded and my guess is that the one that I'm working on was on it's way to that same fate, but sustained the damage shown before it could implode ? Thoughts from suspension tech's ?
