Here's a little update ... I now have approx 350 miles on the bike with the QSC primary ... I've removed the clutch cover every 60 to 100 miles to inspect the inside of the clutch cover & the belt ... and I'm happy to report that the inside of the clutch cover is still as clean as the day I first installed the QSC clutch.

.... and I've ran about half of these 350 miles using the stock driven with a 650 helix & a stiffer spring QSC sent me and the other half of the 350 miles using the STM driven with an engine breaking 50/40 helix.
So if anyone out there wants to try a CVTech clutch, I have one for sale with some additional parts.
