hesitation from 4300 to 5000 rpm

78 Z1R, kerker headers, cone air filters, jetted the rest is stock.
From 4300 rpm to 5000rpm it hesitates if I keep it at that engine speed. After that it climbs smoothly up to redline and before that it runs smooth also. When accelerating through that range smooth also. What can I do?
Check for pictures in the gallery. I couldn't upload picture here (size)

Midrange lean-ness(sp?), try pulling the needles up one clip. Could be as easy as that:laugh: but usually NOT for me:evil:

Good luck!
