i have an 05 rx1 with a 136 track with stock gearing. the clutch setup i currently have is Dalton DPYR Clutch Weights (66gr), Viper Primary Spring, Dalton Black Secondary Spring, Dalton 53/44R Helix. i bought the sled setup this way and it worked great. the problem i have is that the last time out i blew the belt and some cords wrapped around the shaft on the the secondary and caused the clutch to come around and it broke the ears off of the helix. i tried contacting the previous owner because i am having problems located this helix. Does anyone know where i could get this helix or something that is close in comparison???
