I just had to change my first rear tire and previously the dealer adjusted the slack during a maintenance for me so I am unclear as to what the actual slack should be. I saw the manual directions to a t, but the chain seems awfully tight for me for an off-road bike let alone any bike. several people on a Facebook group have said that the directions that KTM gives you are ridiculous and not right. How much slack for deflection to the bottom of the swing arm do you guys run? Right now I'm at 5 millimeters deflectionfrom chain at rest to chain pushed up towards the swingarm per the manual and it seems super tight.
