Manual says 95mm-105mm stock. That is a big difference. Anybody know for this bike and year what a good setting was?

I would use 100mm.

Sag has a workable range. For the sharp turning rm's, that's not too bad. 100mm as stated is the starting point, but don't be afraid to try more or less depending on the track you are riding.

Thanks I will give 100 a try and go from there. Got new springs front and rear from race tech and set my sag with my GF help with a tape measure. Not sure what was wrong but checked it with a sag scale and it was 114mm. Was having trouble feeling like it was kicking on the take off of some jumps. Made it 105 and it seems better but not perfect. Maybe its in my head.

I know now the Hondas are running like 107 and heard that in the 90s they would run like 98 or something so was thinking 105 may be still to much for me.

Thanks guys

I ran 95mm sag on a 2017 yz250f for an AX setup. He got a podium in a lites race. The 2t bikes can work with 90mm depending on setup. See what's best for you. Every chassis is different , and will respond to the sag changes good or bad. Another key is rider. Your particular riding style plays a major role as well. Carmichael rode the kx250 with up to 125mm of sag. He was pretty good on it.

Kicking off of jumps indicates the need for more rebound dampening to be dialed in the shock. Try a couple of clicks at a time. Remember that the 100mm sag suggested setting places the dampening in the correct location of the stroke.

Yeah I figured that I need to mess with rebound but wanted to get my sag set correctly first. When I sit on the bike the rear end just feels high and hard as well im not really sure what is up. I need to check the static sag (I think is what its called, from bike on the stand to bike on the ground) I think that's supposed to be like 30mm or something.

Then just start playin with stuff. Its all confusing

Like PawPaw mentioned, the sag setting is to put the shock in the proper position in the travel to move properly. The damping affects how quickly the shock moves in response to forces acting on it: compression damping slows down the travel on impacts, rebound damping slows down the travel on its return back to the top. Clicking inward (clockwise) slows down the travel.
Think in those terms and you'll gain a much better understanding of suspension and how it works. Keep in mind that all the adjustments interact with each other. For instance:
-More sag makes the shock feel "springy" or "lively," whereas less sag makes it feel "dead" or "slow."
-More rear sag makes the front end feel lighter and the front tire have less bite.
-More rebound damping slows down the kick but may also not allow the rear tire to return to full travel between successive hits. You may feel some side-to-side motion in whoops because of this.
