Elka.the shock needs to be able to be lengthened.changing the dog bone length changes the ratio the how the shock/spring acts on the rear suspension .When i lengthen the dogbones for the drags it feels harder.

That is correct.Fitting longer bones positions the bottom of theshock even closer to the axle of the swing arm.It is harder to compress because the "leverage"(the distance between the turning point and where the force is applied) i shorter now so the torque applied to the shock is lesser.
I suppose it is a good thing to be harder for the drags right??
