Everything will vary with bike design and style. I spoke to a fox expert for mine and he gave me a base setting to begin with than tune which is as follows
Bike:commencal supreme DH 2011 (V2)
spring: 250lbs
Shock:2011 none kashima RC4
Starting/base settings
BV pressure 150psi
LSC at -8
HSC at -6
Rebound at -6
BOC -4 (completely open so none)
*all clicks are from the full closed position, so count backwards (negative) clicks.
Current settings are accurate guesses but may be out a little.
BV pressure 170psi
LSC -9
HSC-6
Rebound -6
BOC -4 (again fully open)
I need to re-look at the rear though I'm not 100% happy with it. Im going to test the recommenced starting point again and tune a little more.
If it helps
If you want an approach method
Approach it like this:
1)You want to run zero BOC right? And you want to run a max of say 150 PSI. So start with these settings and don’t change them through the testing of the HSC/LSC.
2)Sort out your rebound setting, and leave it, don’t alter through the testing of the HSC/LSC.
3)LSC get this dialled before playing with the HSC. I’m suggesting -8 as a good starting spot.
- Make sure your bike has fresh tyres on it that work on your test track. This will greatly influence your LSC settings, so you need to rule out “tyre testing”. Likewise your tyre pressure (measure it and record it), if you’re not working with constants here you’re wasting your time.
4)With the above sorted move to HSC, are you reaching full travel? If yes, increase HSC. Is the suspension sinking under you and lacking support? If yes increase HSC.
Are edge impacts too harsh, or is there a lack of compliance? If yes reduce HSC.
5) Are you lacking support but increasing HSC makes edge impacts harsh? If yes increases BV pressure
6)The suspension is compliant on hits and is not blowing through travel or lacking support but feels it bottoms out a little too often, if yes, increase BOC
