Slow rebound.

[putzer]

How slow does your rear suspension extend? 2008 Phazer GT, 3,600km, front coilover set at stock which is the least preload. Rear torsion spring set at high, the most preload. When you push down on the rear suspension it comes up pretty slow. I've had the entire skid out and greased everything. I even put grease fittings in the bushings on either of the rear mounts.

I have motocross bikes and I play with the rebound damping to make sure the suspension doesn't packup (too slow) or kickback (too fast).

I have not actually driven the phazer yet but it sure looks like the rear suspension is going to packup when you hit a series of bumps.

I would think that as a shock got old or worn, it would lose some of it's dampening, and therefore rebound quicker. Therefore I think that since mine is so slow, it was designed that way from the factory.

Anyone have any insight.

If this is true you will be lucky. The Phazer has a notorious lack of rebound dampening and it kicks the back end around pretty good. Most people that ride the sleds hard at all have to have the rear shock revalved to add compression and slow the rebound dampening down. At least I know I did.

Me too.

Mine was all revalved. I have a rebound adjuster on my front Floats that realy help. Most people don't understand the difference in the adjustments. I made a whole post at one time about suspension adjustment

Can you post a link please?

Heres a better breakdown was to busy earlier to adresss it

Slow speed is for little bumps, high speeed is for BIG LANDINGS

#1) When your sled is squirrely it almost always means your rear shock is not stiff enough and/or your center shock is too stiff (the two shocks are out of balance with each other). You must find a better balance between the two shocks. I might start by softening the low and high speed ajustement on the center shock. Maybe 1-3/4 turn out on high speed and 8 clicks on the center screw. Loosen the center spring so it is just held in place with the skid in the air.

#2) Run your rear springs in whatever setting keeps the rear arm off the rear coupler when sitting on it. Adjust the rear high sped nut to 1 turn and the center to 4 clicks. I like to slow the rebound on the rear, but this requires tearing the shocks apart and revalving.

Every sled wears differently so you should watch for the following signs.

1. Does your sled's suspension start to feel lifeless or packed up after pounding through more than 4 or 5 consecutive moguls or holes and then start to feel OK again after a few minutes of smooth cruising or after stopping the sled for a few minutes?

2. Does the skid sometimes just bottom on small bumps or holes when it really shouldn't?

3. Does the rear sometimes just suddenly kick up in the back....in situations where it did not used to?

4. Does the skid "clank" on medium to big jump landings even when you are landing fairly smooth?

If you answered yes to these questions then the shocks need to be rebuild before tuning can begin

What if after storage once i take if off the blocks the sled just bottoms out when i sit on it and when i get off it dosent come back up? i weigh 170LBS ? I have an 09 Phazer RTX i put 600kms on it and then snow was gone.
