You can never set this up by not riding sections you need to make a note each time of how the bike feels when riding the same section. It took me a few rides out before I dialed in the perfect setup on my 2017 Factory 300. I like a very active back end so nice and bouncy, but still wanted it to damp enough on the way back up. Now I have loads of grip but enough rebound to kick over steps etc. Take some tools with you pick some ground that covers steps, climb, roots etc and keep going over the same section until you feel the bike is doing what you want it to do once you have the back dialed in then set the front forks to match
