i had the wires crossed on my 900 and only two cylinders were firing. i got the same backfire when i shut her down. rewired the cylinders and she runs great maybe a plug or plug wire. pull one plug wire off or quickly feel the exaust to see if the one opposite to the glowing is hot or warm.

On the 750 twins both plugs fire at the same time, so if the timing was off on one cylinder it would be off on the other one also.
Spray some ether/carb cleaner/propane (from a propane torch) between the carb and the head on the side that's glowing while it's running and see if the motor speeds up.

Thanks for the replies. I tried the wd40 idea that I had read in the archives and I did not get any change at all, I sprayed it on and around intake boots, I will try the starting fluid next. I do have a extra pair of used intake boots, Should I use gasket sealer between boots and engine when reinstalling ? So bad valves would not cause this? And also I should mention when engine is warmed up with choke off, bike idles at about 3000 with idle adjustment turned all the way out. And pilot is about 1.5 turned out, I assume this high idle could relate because of a vacuum leak. Once again thanks for the help.
It could be the valves need to be adjusted, do you have a manual to guide you thru this? If not go here and take a look. www.kz400.com It has manual pages you can look at.
When you say 'intake boots' I think of the rubber boots between the carb and airbox. When you say 'intake manifold' I think of the hard rubber connection between the carb and head. It would not hurt to put a light smear of hi-temp sealer between the intake manifolds and head surface, as long as the manifolds are not cracked and leaking.
