i have a 99 400sport with dynoport pipe and v-force reeds. i'd like to do some clutch work. faster clutch responce. but i don't want a high ingagement rpm. because the pipe make good low-end. any help would be great.

 

Anytime you buy ANY pipe that requires NO re-jetting,it should raise a RED flag about its performance value?And Dynoport claims that their pipe needs no re-jetting?Thats very true,however,for 300 bucks,there is a very SMALL gain in performance compared to a HDP or PSI pipe/silencer,which requires re-jetting.I know,I made the same mistake.I sent back my Dynoport Pipe/silencer and now have a modified PSI pipe w/Scrambler silencer and the quad has 3x more acceleration than it had with the Dynoport pipe.

Clutching?
Call Rick Ritter [RcR racing] at 1618-644-3211 and talk to him about the clutching.He'll probably tell you to buy a 25 dollar white or green primary spring.
