I know suspension on the WR is a big topic here, but I couldn't find anything on the Gold Valve kits that Race Tech offers. Has anyone tried them? I have the '05 450 with stiffer springs front and rear, but have done nothing else and looking for a little more without spending a lot of money for revalving. I'm 6'3" and 215lbs and do alot of GP's in So. Ca. I'm not a big jumper, but I do alright for a 47 yr. old that has to work on Monday. Also, any experience with this kit offered by Smart Performance that I read on another thread? Thanks for any help/suggestions!
