Need help with getting my susp a little closer to my weight settings.

im 140.

My back and arms kill after 2 laps lol.

I know i need to tune my damping an compression in such a way I cannot get right.

just need to know which settings i should start with first, an then take what direction in what situation.

You are too light for the stock springs. That's the first step before tuning the clicker settings. According to the racetech and mxtech spring calculators, at 140lbs you need .40 fork springs and a 4.4 shock spring.

The stock springs are .42 and 4.7 which are for ~170lb rider. That's most likely one of the reasons you arms and back are sore.

Once you get the right springs installed, set the sag on the shock around 100mm then start playing with the clicker settings.
