Most likely one of the new vacuum lines came loose leaving you with a vacuum leak. The engine pulls in extra air through the leak, but since that air does not pass through the carb venturi it does not draw in extra fuel with it. Therefore the engine runs lean. Lean engines run hot.

SOURCE: how do i hook up the fuel line and vacuum line on

the fuel line(the bigger of the two)which will come from either between the carbs or offthe left hand carb,is connected to the main fuel tap(larger outlet) and the vacuum line will come from the front of one of the carbs(on the engine side)and should be tapped into the inlet manifold,this pipe (smaller dia)goes to the other outlet on the fuel tap,these are a vacuum pump inside the fuel tap assembly

SOURCE: my 78 kz650 turns over but does not fire. what

Friend, There could be two reasons for this. One. There is no current reaching the spark plug and thus there is no spark in the cylinder. Please remove the plug and connect again tot he HT wire. touch it to the body (metal portion) and turn the engine. If there is spark, it will show as blue flame between the points of the plug. Two. There is no gas reaching the cylinder. Ensure that it does reach there.

SOURCE: i need to know what

Carb sync should be equal on all carbs. If you are refering to the mixture screw settings, they should be 2 1/2 turns out from lightly seated.

I have a 1977 kawasaki kz650 that i just bought found that the battery was dead and jumped it but still have no power no lights nothing what could be the problem


Hi, Steven before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand, clutch, neutral safety switch.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter motor or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. Faulty ignition relay.
14. The electric starter is working but starter clutch has failed.
15. Check for engine trouble codes.

1982 kawasaki kz650 that has a issue idleing


im about to sell my 78 650. these bikes are so called cold blooded and need some time on the richener. its not really a choke to warm up somewhat. if you ride it for like 4 mins and you cant shut the richener off you have a clog someplace or your jetting is not rich enough. does your bike have stock intake and exhaust? if not you need to rejet for changes to them.
