I'd love to try that new roller secondary on the turbo viper. Will have to do some pricing. I also have this roller kit that I had on my 185 HP SRX that I found in my many boxes of parts.. I really like the adjustability of this kit. I put it on my Viper clutch with the Hurricane purple spring. Has a straight 43 degree helix. Lonn at Thunder says he might have a 45 degree helix. Might try that one too.
I will try it next winter. It was from Thunder Products.
Hauck power sports has a roller you can add to the secondary clutch wich looks just like the one on the side winder. I had it on my srx 700 and srx 600. Worked very well. You can use the normal yamaha helix or aftermarket one. I dont know if it will help any on the viper??
