Yeah...I guess the danger is not knowing the specific differences (if any) of the two methods of making the adjustments. I'd be willing to go with the non-knock hole process by using the pulley instead of the knock holes...however I ordered one of those T2 Racing pulleys because mine is a little bent out of shape and anyway the T2 ones allege to produce more bottom end they say "By changing the stock characteristics and making the RC valve movement wider, we are trying to increase the torque from the bottom to the top!!!...but note these pulleys don't have a hole for a 3mm locking bolt or screw.



I'm very interested to try the bike without the RC Valve operating and if it is indeed more two-strokey then I'm all for it. (As long as it doesn't high side me to the stars)
