Thank you for posting your observations on the newer 686 vs 708 Gen motors. Good to hear your enjoying your new machine..
There are plenty of clutch mods that can be done to give you more bottom end torque. The easiest is to start with a 1mm or 1.5 mm clutch shim. Cost is less then 5$. A stiffer spring also helps. Most get the Epi purple witch is 30$. Many do the spring and shim together. But I started out with the shim for about 600 miles before changing to a stronger spring
Oh, and Lighter weights are another easy mod that will help wake up your CVT.
I run a Coop45 machined sheave witch gives me 30% lower initial cvt ratio compared to stock.
