I think it is something crazy... like 12.

 

Mine was at 12... BRB, gonna try it at 4.

I had my rear set pretty good with the stock spring.
Rider sag at 97mm. Bike sag at 32mm and I'm 190lbs.

 

I am going to mess with mine too. I noticed the screws on top to allow the pressure to equalize are not a straight shot with a screwdriver. I guess I need to take the bars off to do it. I am waiting until I get a stand.

 

Ok I messed with mine today. I backed them all in to see where they were and then after reading the manual reset them.

On the 2006 8 clicks out is the factory setting for a 150 boy. Mine was at 12 I am at 4 now.

At the rear compression is at 12 and rebound 16 (I think that is the correct order) my compression was 12 and rebound 10. I am now at 8 and 12.

As a start now I decreased everything by 4 clicks. My preload is about in the middle.

 

It should make a world of difference... especially in front!

 

I only weigh about 165 but bottomed the front out at least 6 times in yesterday's desert race. I think I need to do some adjusting or spring changing.

Factory settings/springs suck.
