Is this tach calibrated??? Would hate to have you spend $100 on weights and not have it be able to pull them... my brother had a almond/blue. In heavy wet snow it was a tad low on rpm with the almond/blue and 62's.
Took the sled for a rip this weekend with the new weight and love it. pulls hard right to 70 mph (i know speedometer are off but u get what i mean) and got it to about 80 at 8000 rpm fast enough for trails around here. From mid to high throttle pulls hard with not much track spin. All around really woke the sled up with the 10-62 weight.
The hole in the secondary clutch determines the preload on the helix spring. The stiffer the spring along with the spring located in the higher number hole (SLP Helix is numbered 1 through 5) will give you the fastest back shift which means that as soon as you back off the throttle the secondary will move the belt to a lower gear faster meaning the sheaves will close faster and the belt will move to the top of the secondary faster. I put a silver/blue spring in my Polaris secondary along with a SLP 40 50/34 black anodized Helix and the sled is so much more responsive now then it once was. It downshifts so fast that I have full power always available right away when I hit the throttle. With the stock soft Red secondary spring it felt mushy in comparison and would linger a bit before it would downshift meaning it would be a bit flat out of the curves no where near as responsive as it is now. Madcow recomended the new set up and I really like it. My sled feels like a totaly different sled now and it pulls so much harder when acelerating on the trails out of corners and when just speeding up on the trails.
