rear suspension

[Blue1]

I had friends help me with some laden and unladen suspension sag measurements and want to decrease rear shock preload to a specific wheel travel dimension, but I don't know the ratio of shock travel to wheel travel. Anyone out there know this?

Also, I need to know the thread pitch of the shock preload adjustment. How much preload per whole turn of the adjuster ring?

Thanks,

it's always better to record actual measurements than building theories.

I would just get somebody (who can read a tape) to measure, and do the "measure-adjust", measure-adjust" until you get the laden sag you want. Going to have to get on and off the bike a few times with your gear on but about the best way to do it. Won't take very much turning of the adjust collar to make a fair change in sag. My

I am aware that measurements is this best way, I had friends over for a party and kind of enlisted them to help me get baseline measurements. I didn't want to tie them up forever, three of us did it in twenty minutes for the 'busa and the 'rex.

If I had that info, I could have changed the preload to where I wanted it, then confirmed and fine tuned it when I had help again. Trying to explain to a wife and one or both teenage boys how to help with this would be an exersize in frustration
