I was reading the whole Vmax performance guide the other day and am curious about this topic also...whenever i get a chance to start my 87' project that is. Do you still have to modify the Primary clutch Spider for the "special" primary spring they reccomend?? Or is there a clutch spring to use in the stock yamaha comet that works good for the claimed 8-1/2 horsepower increase?
