Weird. Adjusted the suspension per manual, less than 170lbs. I can push on the back and the bike will bounce 1 and a half times. It feels REAL soft. This normal? I'm light guy, 150 with all my gear on.

I can increase compression and rebound and it does get stiffer.

Ride and see. Slow inputs like pushing on the bike get different reactions than the faster / higher frequency inputs of an actual ride.

I set my bike up for 170 or less and I don't think it bounced when I pushed on the seat. It just went down and came back up. Your bike sounds too soft to me.

I have noticed differences in ambient temperature effecting such suspension response.



By chance is it over 150F degrees when you are located?

I cant wear short shorts in the summer without underwear for the same reasons.

Dre,

You are adjusting the damping by backing the screws out the specified number of turns, counter-clockwise, after having turned them full in clockwise, yes?

Doing the opposite would explain the behavior you are seeing.

Lets see.. Compression, I turn it as if I'm tightening a screw, and then back ou the number of turns, 20 full turns.

Rebound, same thing. 3.25turns CCW for adjustment. If I use the 270lb weight setting for both, its stiff as a log.

I'll check with the dealer tomorrow morning, see whats up.

Dre that's 20 CLICKS, not TURNS....
Seems it something like 6 cliks per turn.

Only thing that is clicks is the rear shock COMPRESSION: CLICKS OUT FROM MAXIMUM**

All the others minus the rear shock preload is turns out or in.

Krassh - Compression is what I and Dre were talking about.

He said 20 turns, I replied 20 cliks.
The other adjustments he mentioned were turns and OK...

Sorry, 20 clicks. Its impossible to turn it 20 times full revolution.

Today, the suspension seemed stiffer. I have a feeling when the bike gets real hot/hot day, it softens up back there. Hmm..

Before you ride, it feels much stiffer on a cold day than a warm day. As you ride on a cold day the suspension oils will warm and it should soften up.

"I have a feeling when the bike gets real hot/hot day, it softens up back there."

As will virtually any suspension. Warmer oil is less viscous. Your owner's manual even mentions this phenomenon and advises that some compensatory adjustments are a advisable for colder or warmer temperatures.

Does the rear shock see much engine heat?
