Shockwave

08 Nytro MTX MCXpress 240 kit. What secondary spring should I be using? A part # would be greatly appreciated as well.
Thanks

EPI purple and wind at 1-0 as the timing of a cat spring and Yamaha spring are different. Get a buddy to help winding the secondary......its a bugger.
2 Turns out max max on the shockwave. That portion will depend on primary set up.

I have found that the cat green seems to work better and last longer than the epi.

I'm having trouble getting the cat green from the local cat dealer. Do you have a part #.

AC Green part # AC-0748-025
Force on AC green and EPI purple is similar, with EPI a little softer, 157 vs 148lbs @ 1 7/16".
