I need an opinion on spring rate for my 01 YZ426F. I weigh about 215 without gear and ride intermediate MX. I have the stock springs currently installed(.46kg/mm front and 5.4 kg/mm rear)and the valving is stock. My race sag is currently set at 98mm and I measure 5mm for the static sag. The static sag indicates I should go to the next stiffer spring. The MX-Tech site spring rate generator gave me .4693kg/mm for the front and 5.54kg/mm for the rear. Should I go to the 5.6 rear? I've seen .46kg/mm and .48kg/mm listed as available spring rates for the front. Should I leave the stock .46 kg/mm in the front? If I change the rear to a 5.6 will I need to add any preload to the front. There is currently no preload in the stock front. The bike seems to ride O.K. the way it is, but I was considering changing the rear due to the low static sag reading. I set the race sag with my gear on. Any opinions?
