Results of the rear Fox 2.0 valving change are in, and first let me say, I am so far VERY happy with the results of using the following setup/valving!
NEW SETUP:
Fox 2.0 7/8" shaft
175 TOP spring, 10" long
100 BOT spring, 16" long
Crossover set about 1.5" above contact point at sag
Steel valve piston with 1 factory 0.070" bleeder
#30 Rebound valving
#30 Compression valving
Nitrogen pressure at 150psi (Suspension lifted off the ground!)
ORIGINAL SETUP from
Dave-CoFox 2.0 7/8" shaft
80 TOP spring 12" long
100 BOT spring 12" long
Crossover could not be engaged
Steel valve piston with 4x 3/16" drilled bypasses
#70 rebound valving
#50 compression valving
Nitrogen pressure at ????PSI
So, I went into this stone cold with no idea really. I'm not really a shock guy. Not really a suspension guy, but I do like to tinker. The OLD setup was very bouncy. Bottomed out really badly over almost every bump. Replacing the springs initially helped a little, but the suspension still bottomed out, bucked like a bull ride, and never settled. It was QUITE a terrible handful to say the least.
So, threw in the NEW piston and #30/#30 valving. Right off the bat, it felt SOO MUCH BETTER! Un-believable how much of a positive difference. Rebound is quite smooth and predictable, though maybe just a tad bit of a hair on the slow side. I may consider trying #25 rebound - not sure. I might just leave it alone. Compression felt great as well, but just a tad bit too hard initially, and it was only traveling about 80% over jumps. Initially, I had my crossover just 1" above sag, and N at 200PSI. I lowered Nitrogen to 150PSI, and then raised my crossover to 1.5" above sag. BINGO! Now over the same jumps it will compress down to 100% travel and un-noticably tap on the bump stop. Compression feels Perfect!
Now that jumps and big bumps are ear-to-ear, I still have to think about something. In rumbling sections, like just blazing down a rough cut trail seems the suspension it just a bit on the harsh side. I'm may keep everything as it is, because its surely so much batter than before, I'd really hate to mess it up... But I somehow just wonder if a second 0.070" bleeder would smooth out those rooted trails a bit, and also increase the speed of rebound (Which I think I need just a tad bit faster rebound). Surely though; if I add a bleed then I may need to raise compression to about #40, raise N to 200PSI, and maybe play with the crossover.
Thoughts?
