HELP!! ISSUES!!!

MY KZ400 IS RUNNING LIKE COMPLETE CRAP! SOME TIPS WOULD BE GREATLY APPRECIATED!

Sounds like the choke is closed.

have you tried adjusting the idle screw?

choke is closed. bike turns off when choke is open, it runs at 1k when cold but run at 3-4k after it warms up?

This was a running bike before this issue?

Check for a vacuum leak,some of the spray carb cleaners have had the formulation changed by EPA mandate, but read this method of vacuum testing:


(Using An UNLIT Propane Torch For Vacuum Leaks)

Use a fresh set of sparkplugs, and check the input voltage of the ignition coils too.

Testing Kawasaki Ignition Coils For Input Voltage

When voltage testing Kawasaki Ignition Coils, the following needs to be done:

1. Remove the fuel/gas tank to access the coils.

2. Fully charge the battery.

3. Using a multimeter, set it up for VDC(Volts, Direct Current), range of 20.

4. Turn on the ignition switch and the run/stop switch to “Run”.

5. Put the multimeter’s RED probe on where the red or red/yellow wire goes on the ignition coil.

6. Put the multimeter’s BLACK probe on either the battery Negative(-) post/terminal or a good frame ground.

7. You should be able to see battery voltage at the ignition coil connection, but this depends on the current draw of other items in the same circuit.

8. If the tested voltage is down to 8-9 volts, you probably need to clean the many and various electrical connectors.

9. To check the spark output at the sparkplugs, use these:

(Using the Thexton 404 Spark tester)

Instead of grounding the sparkplug with the sparkplug wire attached, looking for a spark. This method puts the IC Igniter and ignition coils at risk of failure due to high currents, and possible internal shorting.

The sparkplug caps contain a non serviceable 5000 ohm resistor, that can fail due to age,heat & vibration. Tese can be checked using a multimeter, after they are unscrewed from the sparklug wires.

the bike was running and i would idle right, im thinking it might be dirty carbs?
