So if the machining has to be done professionally, my option would be Mountain Perf, unless there are others that don't require machining.UP bushman said:Mine is a Hauck Magnum Roller and it is sweet and uses the stock Yamaha helixes.
I live in the US and sent it them to machine and install for $60.00. For you Canadian's not much of an option sorry.
well funny you should ask upbushman, was just thinking of digging into clutches again. we just finally got snow, and i dont remember what helix i ended up sticking with last year. lol I'll update you when i figure it out. What i can say is that no matter what i did i was never able to get completely get rid of bog when climbing in steep deep(under heavy load) but got pretty close. let u know..

Could be to tall of helix causing it to shift out to quickly and not hold rpm under load. I had the same problem with a 43 degree helix under load. I had it set to 11,800 rpm holeshot and 11,600 rpm on top end on the flat with 11,300 rpm under load which is not bad. I want to hold 11,600 rpm under load on my sled with mods and it still pulls 11,300 rpm. I have a 39 degree helix in it now just need to do some more testing.
I am a biscuit at 300 lbs with all my gear so a 43 degree helix would work if it were a lighter rider. It pulls wicked with the 43 degree helix setup to top end. I may go with a multi angle helix like a 43/35 if I get the 39 degree to do what I want let you know.
