well went lake racing down the lake with my ext. this thing has144 inch track. did really well. raced against an 05 sno pro.mine is 05 as well. as you can see my name i have a crossfire and raced it. did good with it for holeshot but never really had top end. ok ok what i did was i took my secondary and primary and put it on the ext. and my reprogrammed ecu. and man it pulls real hard as for top end it has more but had to let off. 73gram big dogs.orange spring. shaved primary.which makes my engagement at 4800rpm the reason for the shaved prim is because of the ecu. it has a bog when the engagement was lower. cdd75 helix 034 belt i think can't remember. just got the sled. and that is what i got for clutching is it any differt with other ext's i know the original had just stock cluthing just the spring was black on the primary. :super_happy:
