I took the bike to the dealer today to get the clutch kit installed. I have ridden it around today after the install and can say that low end torque is definitely improved. The secondary spring that came with the kit was around 1" longer than the stock spring. Also, the stock rollers were 1.183" on the O.D. and .714" on the I.D. The kit rollers are 1.1" on the O.D. and .553" on the I.D. The widths were the same. The kit I got from Speedwerx is there part number CKA700ATV-2. I was afraid that after spending the money I would not be able to tell a significant difference, but you can.
