Last year I ran a 151"x 16" geared 19 38, team clutch took the red black out and put in soild black. 70-48-36 primary is a black with green stripe, with 64 gram weights, sled ram 8100 rpm.

This year I put a 162" 2-1/2 15" geared 19 42 same clutch set up! sled only runs 7500 rpm. I put a almond spring in the primary that helped the engagment. next I put the Helix in the 66-44-46 seld ran 7700 in powder next put in 62 gram weights sled still runs 7500-7700 on a load but on the hard trail pulls 8500+rpm

Anyone got a idea on how to get this thing back to a steady 8100 on trail or climbing the hills??? Whith out going back to last years setup!

One thing you should notice is the helix with jump off the 70* angle much faster now with more gear , 800 motors need to be loaded hard and you can do this with helix finish angle. Going from 48* finish to 44* is huge! try the 70* helix with 62 grams in the primary.

Get rid of the flatlander helix, put a 58/40.46 in there and the R's will come back and the belt temps will go down. Might even be able to swing 66's.
