I have the 06 GT big boy spring and had rebuild and originally thought it was severely harsh and rough and would bottom on multple hits. Mr sled and I turned out my rebound and less bottoming and less harsh on multiple impacts.
We came back on a rail road grade whooped out bad and I could run 50 -60 70 with great controll and no bottoming.
Now I am wondering how far out I can take the rebound before I lose ride or performance, What will it fell like?
I started another thread before I read this one
Any insight is appreciated

Too little rebound will cause the rear end to kick around on bumps like a pogo stick. If the seat is throwing your butt in the air like a mechanical bull, you don't have enough rebound.

I ask a question on Yamablog and got this response about yamaha valving on there shocks..
Most Yamaha shocks are now using pyramid stacks in the past this was seldom used.
Ohlins, Soqi and Fox pyramid stacks have been common, KYB in the past few years have offered pyramid valve stacks.
The 2 adjustment used to adjust calibration is (1) piston - number of bleeds and diameter of bleed holes (2) valve stack or shims - 2 types of stacks are commonly used the straight stack were 2 different shim sizes are used and increasing or decreasing the number of shims to increase or decrease force, or the pyramid stack shims start from the largest diameter to smallest in diameter more progressive type of damping force.
Some shocks offer external compression and rebound adjusters but the adjuster influence both high and low speed damping force
We don’t have shocks with external slow and high speed compression adjusters, but I don’t believe any competitors are using these systems
I’m guessing as to what Brians question is and only answering by the difference between Yamaha and our competitors was in the past.
