installed 444 kit with 13.5 comp piston. went to dunes this weekend now bike feels flat on topend! plenty of low end! bike has hot cams,jetted,k+n filter, factory pipe with pmb cap. anyone had this issue with big bore kits dropping power on top? wondering if head or pipe is not flowing enough for the increased cc's?
