07 yz450fw , being riding in forest and now on a track. The rear sag is 107mm and i notice on a video we shot last ride that the back is nearly full compression a a jump or too. So i plan to get it at 90mm with 25-30mm static. The spring rates should be close to my weight , So with this model do these figures sound ok or anyone else got better figures to follow. I want to set in once and learn that style. Also to make up the 17 mm sag how many turns on the spring nut would u go?
