since you are running the new yamaha hyfax's if they are comparable to hyperfax slides you dont need to run any idler wheels. 2000 miles on mine last season with very little ware, the season before I was running regular slides and was going thru them every 500 miles, last season switched to hyperfax slides after the first set burned down to my rails and havent worried about my slides since. this year Im running an arctic cat suspension and the first thing I bought for the new suspension are hyperfax slides and Im going to be running them with zero idler wheels. thats if we ever get snow.207nytro said:Looking to possibly install some extra idlers on my nytro since installing the 144 extension. I am looking to use the stock mounting brackets that i believe are used on the stock idlers. Was just wondering if anyone has any ideas on installing them on the inside vs the outside of the rails. they would also be installed at the tip-ups and be used in conjunction with dupont hyfax and scratchers. Pictures would also be nice! Thanks!
