Rollers are crazy expensive though. I wonder if gold is less by ounce!
Yes they areAngles are same?
I was going to start a new thread on this but came across this one. Did you find out how the Hauck roller did on the Viper? Is it worth doing. I have one at home that I had on my SRX and would like to try it on the viper once I get it on snow. I know the shafts are different for the 4 strokes but are the helix's the same? I have a ton of them to try out as well. I also have another roller I could try as well. Basically bolts to your current secondary. No modification needed. That one has the cat style helix on it. Much like the Yamaha roller rooster. I would be interested on your guys opinions on this and hear from someone who has had them and what they liked and disliked about them. Thanks Rob
I had one on my '98 Cat ZR600, it worked very well. I wonder why Thunder stopped making them? I would buy one for my Viper if still available.Thunder used to sell these way back. But they work great. Encapsulated roller clutch kit. I got one of the last helixes before they stopped making them.
