Question about 1991 kawasaki Zephyr 750

1 Answer

Have a vaccuum line that goes to nowhere from what looks to be between #2 and #3 carb on my 91 Kawasaki zephyr 750. Bike runs with hose sucking outside air but wants to stall if plugged. After going for a ride it also seems to spit gas from hose. Where does it go to.

G'day,
Usually there is a hose that connects to both number 2&3 cylinders at the front of the carbies.These two hoses commonly join together with a tee connector & a single hose comes off this tee. leaving this hose dissconnected allows the engine to **** air.This air is being drawn directly into the engine-making the mixture incorrect(too lean),as this air has not had fuel mixed with it.Therefore it needs to be re-connected to its original position(or at least pluged).
Generaly-Here in Australia- this hose connects to the fuel tap to a small spigot at the rear.
This type of fuel tap only allows fuel to flow to the carbies when there is vacume applied to the tap by that hose.This is to help stop the chance of the bike flooding.

see the o ring marked part 670- see the part to the right with no number-it has a little spigot on the bottom- Your hose goes there.

Hope this helps
kind regards Andrew Porrelli

Hi, Shazam after careful deliberation 4 out 5 Kawasaki Gods give this one a thumbs up, but just to be on the safe side you should give your local dealer's parts/service department a call to confirm.

Need help with 1991 Zephyr 750. having major issues with taking way to long to come back down to an idle. It seems like its being choked down somehow. what are the jet settings, turns out, etc.. I can...


sounds a bit like its s ucking air, the vac line opens the fuel valve, so I assume you disconect the line and hold your finger over it, and it runs until it gets low on fuel in the carbs.
Maybe the vac hose is leaking on its connection or has a hole, or the diaphram in the fuel tap is gone.

On a kawasaki zephyr 750 set of carbs, where do the two hoses that come from between carbs one and two and three and four go( not the vacuum hoses, or fuel hose. Are these the heater hoses?


They are fuel overflow hoses, and just hang down under the engine. If they are not vacume or fuel lines, then they must be the overflow pipes, one from each carby.

run a can of Seaforam in the tank..purchase from Autozone put in 1/3 to two gallons gas drive it around for at least 10 miles to insure it cleans out the whole carb system.if that doesnt work, check all carb hose fittings when bike is at idle spray some Chemtool B-12 ( also at Autozone) around the carb hoses and manifolds..if idle increses thats your problem. Caution: chemtool is very toxic wear gloves and a mask.

Kawasaki zephyr rpm error. idles at 1,000 but shows 3,500 rpm. sometime goes back what it should be. what is the problem ? let you know my motorcycle is not 750. its Zephyr 550, couldnt find the 550 model...


If your bike has a cable hooked to the tach and not electric then unscrew the cable and take out the inner cable from outer housing and lube it before reinstalling...a dry cable will do just what you are describing....now understand the cable will only pull out from one end..usually the connection at the engine....Good Luck to you friend....Tim

Vacuum line not connected correctly


ok fuel fill lines are the 2 lines between carbs 1 n 2 and 3 n 4 toward the rear of the bike the 2 hoses coming out just in front of them are float bowl overflows that just get criss crossed over the carbs and ran thru the little holders on the frame. the only vacuum line is coming out of the side of carb 4, this line goes to the nipple on the petcock facing away from the knob. as for the fill lines the 1 between 1 n 2 goes to the nipple facing the rear of the bike and 3 n 4 goes to the 1 facing the front of the bike. hope this helps here is a link for a free service manual download. http://www.files.michaelmcmahon.org/1988-1997-GSX600-750-1100F-R.pdf try using www.katriders.com it is a lot more helpful than this site for katana issues.
