Kawasaki Twins Owner’s Forum (KTOF)
I am a member of a small handful of forums related to these old bikes. I have to admit, as time gets shorter and shorter, I have less and less time to frequent them….
Anyway, if you need to reach me, or are looking for a KZ Twin-related forum, come visit the forum where I am most active (especially since I am a moderator), the Kawasaki Twins Owner’s Forum (KTOF)…

Hello,
I have a 1978 KZ750B2. I live in Phoenix, Az, and when I ride it in the heat (105) the idle will not stay steady. I adjust, and adjust, and adjust and get the manual sated 1,000 rpm idle. Once I start riding, this changes (usually drops). Many times it will come to an idle, and then die a few seconds later. When it’s cooler out, this seems to happen less, but it has still died while at idle. I have adjusted in cool and warm weather, and when the bike is both cool and warm. When I’m driving, it runs and sounds fine. I ran the pilot screws out to give it more fuel and have adjusted the idle knob as well. That only resulted in popping and a whisp of white smoke out the pipe when I rev it after about a miute of idle (stop light). Did the opposite, no smoke, still dies. It is missing the decel cable on the throttle, but the spring is stout and it seems to close consistently every time. It has about 32,000 miles on it. I’m guessing the cable, fuel evaporating in a hot carb, or spark plug gap?
Any help solving this would be greatly appreciated.
Thanks!!!
