Hi! What is the stiffest spring I can install in my forks w/o having the need for trimming the spring guides. Bike is ´11 990R. The correct spring rate for me is probably in the area where spring guide trimming is needed, but I have other bikes for other purposes and I just want to stiffen up the 990R a bit to stay a little higher when braking. I have no plans to do any revalve so it´ll be stock. Thanks!
