You may find what you want at this site, but if not, Google "1991 Kawasaki Zephyr 750 motorcycle manual". There are plenty for sale.

check the magneto mate it may need servicing/repair or you may need to change it

Check the battery, it may just be too weak to create enough of a spark. I would try putting it on a tender for a few hrs. You can also check the spark plugs. There may be a fuel cut off switch or a some of other kill switch too. Make sure the bike is in neutral as well

go on ebay great stuff for bikes etc

is there 2 cables at the throttle grip if so one being accel the other decel these need to be adjusted properly to eliminate your problem on my kawi- looseing bothlock nuts and screw both throttle cable adjusting nuts in fully to give throttle grip lots of play with throttle grip closed turn out the decel cable adjusting nut until the cable just becomes tight. tigten lock nuy. turn accel cable adjuster nut until throttle grip freeplay is approx 2-3mm tighten lock nut hope this helps

It sounds like you are running out of battery, and that is why the bike is quitting.

Have you checked the charging?
Check the battery voltage with a meter after you have charged it. should be 13.5 volts or so. Start the bike, you may have lost a little but the voltage should increase as you watch the volt meter, rev the bike, Any increase?
If there is no increase or if it is decreasing in voltage then I would suspect you charging system.

Hope this is of some help.

poor fuel, gummed up carbs. blocked fuel filter, if you in the US get some Berrymans B12 double the dose and put it in the gas, hopefully you can get it to turn and draw it through to the carbs, it should clean them out, also you can try the berrymans spray carb cleaner, remove air cleaner, make sure slider in carb is up and spray a bunch in.
did you have lights when it died or nothing at all?
