That's how I tune my clickers as well. Still learning to tune spring preload though.
there is no spring length as each sled weighs different according to what can you have etc, they say to set 1/4in pre load. That would be with a full tank of fuel etc. the clutch side spring length with be shorter if you have a can due to the weight on that side of the machine, vise versa if you have the stock suit case. there are set up instructions on raptors site. print them off set up as recommend and fine tune from there. I highly recommend running spring spacers with a set of HD springs in the rear end for your weight. we are roughly the same, trust me you ill thank me later.
