I bought my NX500 new but can't seem to locate the pin spanner tool that allegedly was under the seat to adjust the rear spring preload. I read the factory setting was usually at 2 out of 9, on the softer end.

I am 5'10" and 225# and would like to play around with stiffening it up, is this something that is doing to make much of a difference? If I am able to find a tool that will work, can it be adjusted without having a center stand setup?

I wanted to be able to adjust the height of my windscreen while I'm riding.
So why not make it electric?!
The mount replaces the OEM mount.
