So last year it was suggested that I rebuild my brake calipers due to age. One poster put up a youtube of the front wheel spinning without any restriction from the brake pads, so I felt I should look into it. Well I did, and it was a waste of time and money as everything looked perfect coming apart. I had a huge pia as the replacement non OEM parts from Mototbins didn't fit, and finally got the proper OEM parts that went together easily.
I'm wondering about my forks which have received regular fork oil changes. They work fine. What do you think.

Rebuild forks?

Re: Rebuild forks?
I’ve never rebuilt a fork unless,
A) it’s leaking,
B) it’s sticking, or
C) it’s clunking.
This method has served me on both on forks with 1,000 km on them, & over 100,000 km on them...

Re: Rebuild forks?
You might feel an improvement by replacing or shimming your fork springs which have probably sagged significantly since new.

Re: Rebuild forks?
I put the hd BMW fork springs in a long time ago, they seem to be sitting up fine. Isn't the ride height the issue? I'm more worried about deteriorating bumpers and internal parts.

Re: Rebuild forks?
No bumpers, and only about five bits in there. I haven't worn mine out yet.Zombie Master wrote: ↑Tue Sep 11, 2018 1:25 am

Although I did put a 12mm spacer on top of the springs. Noticeable.

Re: Rebuild forks?
Concentrate on synthetic fork oils and you shouldn't have any significant deterioration to the soft parts of the fork.
After 20 years as a professional bike mechanic and 30 years as an engineer I know just enough to be dangerous !

Re: Rebuild forks?
Not easy to find 100% synthetic fork fluids, what kind do you use?

Re: Rebuild forks?
I don't think the '81-'84 has any soft parts. I haven't broken any in my '81. I've broken lots of other stuff tho.
