I don't understand how so many people can have issues with hitting the bump stops so much. With the 912's and daystar spacers I have at least 4 inches of space between the axles and bumps, and they are the whole bumps, not cut, not shorter than factory. I can't imagine that the factory suspension parts had them closer than an inch.
Maybe yours were already cut?
I've never seen a stock/non lifted VX with more than 3/4" between the stop & the axle pad, with 1/4-1/2" being far more common...
