I bought an 08 klt few weeks agao and on inspection, found this big purple spring on the rear shock, on futher inspection it is a hyperpro shock. I don't know much about them, so to ask you that do!!!. What setting do I use on the spring preload for a guy 190 and sadly to say solo b/c wife can't ride anymore neck problems, another story. While I'm at it what do you think for a front shock, the one on now is stock. I love the twisties and ride it hard, always have, excpept when my Lady was on the back.
