ignition trouble? please help!

I ride a 1997 vfr750 and I noticed when im getting on it there is a major lack of power and it hesitates/ surges.. my friend said it is popping out the tail pipe also.
This happens when im accelerating above 6k rpm. it doesn't matter what throttle position im at 1/4 3/4 wot, no matter. but once it hits 6k the power goes flat.
im thinking its not my carbs and maybe an ignition problem. due to it not being throttle position related. any help would be great!
also the bike is having charging issues lately. it has battery voltage at idle to 3k then it only goes up 1 volt from 3k on.. that cant be right and im not sure if its related.... brand new batteries fyi.... I am very mechanically inclined and have a lot of tools so don't be afraid to get technical.

 

What is the actual battery voltage at rest and while idling? If it is less than 12.8 then the battery is at less than full charge and may be laying down on you at 6k rpm.

 

i tested with the new battery and it is at 12.5 key off and low 13's at idle.. it reads mid 14,s from 2500rpm and up.

 

Surface battery voltage with hi-beam on rev'd up to 5k should be 13.5 - 15.5VDC.

 

thanks all! you can refer to my other thread in gen 3-4 for my carb/ ignition problem... still need help there. thanks
