Ok guys I have a 1977 KZ650 with 4 into 1 exhuast and air pods.I have a Dyna S ignition with green dyna coils and the wiredGeorge coil mod.Im running 110 mains and 17.5 pilots in the carbs.Im getting a hesitation at the lower end of the rpm's.I checked my voltage to the battery at Idle and I only get 12 volts until I bring the rpm's up,then it will go up to 14.3 or so.Would that cause the hesitation?Or should I play with different jet's???
That's completely normal. At idle, the alternator doesn't put out enough current to both feed the electrical system demand and also pump up the battery. If it goes to 14V +/- 0.5V at higher RPM, it's working right.
It can't cause throttle hesitation.

Thanks,Bountyhunter that will save me some time!But where should I start about the hesitation problem???
depends;
Did this setup (pipes and jets) run good before and now doesn't?
Or, did adding the pipes make it run off?
Wired George is da man for jetting. Off the top of my head, a hesitattion at low end could be:
pilot jet size too small
needle position.
fuel level in the float bowl

Seems this model (1979 KZ650) could have come equipped from the factory with either type carbs, (1) side located pilot circuit air screw #42 (turn in clockwise to enrichen by reducing air in pilot mixture; turn out counterclockwise to lean by allowing more air into pilot mixture) OR (2) bottom located pilot fuel mixture screw #30 (turn in to lean by reducing mixture; turn out to enrichen by adding mixture).
[click to enlarge]
Edit-- am guessing the bottom located mixture screw version with the #32 limiter cap came on later models designed to comply with the then ever increasingly more rigorous EPA regulations.
