Stick with OEM or is a something like Custom Chrome good too?
I am Howard & I do suspension for a living. I hesitate to post on chat sites because there are so any suspension experts already but here goes. Bushings & seals:35K miles
And you know this how? Have you actually ever tried any thing else? I love these blanket statements, kind of like how Indians killed the buffalo, one goes off the cliff the rest follow.
All photos are from a newer FXD with 6,000 mi on the clock . Not good HD Fork oil, better out there,I'll add that if the only thing you do is change fluid, you're not helping the suspension much. Yes new fluid will perform better but the mud that is in the bottom of the forks will still get mixed into the new fluid and add to the faster wear of the bushing. I changed fluid in '09 when I put Ricor Intiminators in. I am currently tearing the forks apart to put in Ohlins FKC101 cartridges, the cup I drained the oil into has a very thick coating of the metal particles in the bottom and when I pulled the damper rod and oil lock out, there was chunks of packed together metal particles. The only place you can't get to for cleaning or replace is the end of the tube with the check valve. When I knocked it out, it was full of particles too.
