TOPIC:

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!

Did you do some mods that caused this or did it just start?are you going to wot when this happens or just rolling on the throttle?

What is your jetting set up?
