Jag har ju monterat Fox Float 3 fram på min Boondocker 600. Tänkte kolla om nån har tips/input vad som kan vara vettigt tryck i dämparna till att börja med?

Sparat ned samma data som Meanis länkade till förra våren då jag räknade på viktreduceringsmöjligheter/kostnad för en Commander med titanboggie och lite mer, detta är dock ett hyllprojekt då kostnaden snabbt översteg 2500 kr/kg !
Lägger bilderna nedan samt Irondogs råtext på originallanguage här, får översätta senare och lägga det i FAQ.
Antar att Fox Float 2:s uppgifter är direkt överförbara till 3an

This is a FOX shock tuning cheat sheet I put together a few years ago to help people set-up and tune their shocks.
Evol Chamber controls the bottom out resistance (0-300 psi range) Set 1st.
If traveling to quick through travel, increase press by 10 psi
If not using full suspension, decrease press by 10 psi
Main Air Chamber adjusts the ride height (sag), roll/pitch stiffness (0- 150 psi range) Set 2nd
Adjust by 2 psi to rise or lower spring force Ride height)
Temperature Dependency = 1 psi per 10 deg change
Clickers. Adjust 2 clicks at a time, full in (clockwise) is #1
Compression Red knob
Clockwise stiffer
Counter clockwise softer
Rebound Blue knob
Should return as fast as possible with out bucking
Clockwise is slower rebound
Counter clockwise is faster
Too much rebound dampening will seem harsh, washout, & packing
Tuning suggestion:
As a general rule you want as little rebound damping as possible so that the suspension returns quickly, but still enough rebound damping that the front of the snowmobile does not oscillate upon landing. The front of your snowmobile should return quickly to ride-height and then remain still. If the front suspension continues to oscillate several times after landing, try increasing rebound damping (slower).If the suspension does not oscillate after landing, try decreasing rebound damping (faster).This procedure should allow you to close in (or bracket) on the desired rebound damping setting
Symptoms of Too Much Compression Damping
The front end is harsh over small bumps. Shock seems to stay almost rigid instead of absorbing bumps. Especially noticeable on downhill bumps.
The front end is harsh at high speeds over large or medium bumps. The shock stays too rigid and does not use enough travel to absorb bumps. The shock rarely or never seems to bottom-out, even off the biggest jumps.
Symptoms of Too Little Compression Damping
The shock bottoms-out on medium-sized bumps and at the bottom of deep, smooth gullies, or rising portions of deep, rolling whoops.
At high speed the front end takes medium square-edged bumps smoothly, but bottoms out too easily on larger bumps. Bottoms out too easily off jump and at high speeds over large square-edged bumps.
