I rebuilt the forks last week, new bushings and seals.
The original owner had put in firmer aftermarket progressive rate springs as well.
I'm not sure which brand, as they had no info marked or engraved on them, but they are over a quarter inch longer than stock.
With new wheel bearings and steering bearings, and the Centramatic wheel balancers, and Still a rigid ride...all the puzzle pieces came together on the cheap price on this bike, lol
The front tire that I took off looked good for a quarter turn, then was through the wear bars a quarter turn, was good, then bad again...a sign of too much preload and/or compression.
Keep in mind these are Non adjustable forks too, no Compression or Rebound adjustments, and Preload is determined by the spring rate and length.
Hmmmm??
Well, the forks have Anti-Dive, which is what it sounds like, it keeps the forks from diving under braking.
This works through the linked brakes, and has a cylinder on the left fork, which gets pressure applied from the brakes, and keeps the forks from fully compressing.
Well, add in firmer and longer springs, and now the forks cannot compress hardly at all...and the front tire becomes your suspension...hence the out of round wear.
After a quick GW forum search, yep, that's a thing, lol, disconnect the Anti-Dive and it should be good to go.
I did(I made a temporary spacer and ordered the correct one, yes, there's even an aftermarket mod for this), and, what an improvement!
The bike handles incredibly well now!
The suspension works and gives good feel and feed back.
The only thing now is that as good as it is, it's just a little on the firm side, as if it needed a small amount of preload taken out, or even just a couple clicks of Compression (if I could).
Which now brings me to wonder;
If I remove the oem washers that sit on top of the springs; shouldn't that lower my preload?
The stock fork cap just threads in, but with longer springs, a little effort is needed to start the caps, lol, which tells me leaving the washers out will Not cause a loose assembly, but simply take away some of the spring length/preload, and of course the spring rate cannot be changed(I am looking into other springs as an option).
If I remove the oem spring washers, shouldn't that soften the front end slightly?
These simple forks are complicated, lol
@zeepopo2
do you have any advice or insight on this?
Thanks for any info
