I was a little unimpressed with the stock for on mine as well. Ended up replacing the fork internals with the DH comp/rebound for +-$125 much more civilized now!
i read several reviews on the bike and they all said pretty much the same great package but the fork is hurting it , one stated they should have forgone the dropper for a fixed post and used the cost difference between the seat posts and put the $$ towards a better fork .
i dropped my 66CR off at Marzocchi yesterday , they are going to reduce the travel too 160mm and i will use that till later in the season .
and i may look into the upgraded internals who did you source them thru ?
