My 2016 shows no signs of power loss at 11k rpm on the Dyno with stock cams and valve springs. What am i doing wrong lol.

this is strange....my testing never showed any falling off of power with the stock intake. My rc390 pulls to 11000rpm with no drop in power till redline. only mods are air filter/ exhaust/ PCV..
in this video you can see the rc390 actually powering up a wheelie...no rocking/clutching.....just pure power.
