Normal driving around is perfect.  When I drive it hard with a lot of throttle, then back off to slow down, and then try to punch it again, the engine seems to hesitate a bit then it kicks in.  Wondering if this a typical when dropping down from high rpm and braking hard, to kicking it in again.

Mine acted that way when the fuel tank check valve got stuck shut and the pump would make a vacuum in the tank that the pump had to fight...which dropped pressure and volume. Crack the gas cap do it can get some air and try it. If the problem goes away....you have your answer.

I just saw a response that says CFMOTO has a fix for it.  Something to sdo with the air filter  pipe collapsing at high rpm.  Cant find the response now!

Dealer knows nothing about the intake pipe collapsing but did mention that the throttle electronics do cause some delay if there is large quick swings in RPMS.  I am launching fast then brake hard for corners then back into the throttle.  That is when there is a delay before the engine kicks up the rpm again.
