Engine noise right hand side ZZR1100?

Only 3 things to check air, fuel and spark. Check your spark by removing your left spark plug cap and place an old plug in it, then touch it to the side of the block. Crank the engine if you see a spark then, move to the right hand side and do the same. If you have spark on both sides, then both coils should be OK. If no or very weak spark, your coils could be faulty.
If you have good spark, check your air filter see if it is clean. If it looks dirty it is dirty and won't flow good air. If it is oily then your pcv is blocked.
If clean and good, then check fuel. First thing to check is, is there any fuel in carb bowl. On bottom of the bowl should be an allen head screw, undo it only until fuel comes out, check all four (one at a time). If no or very little fuel, then maybe your needle and seat are worn or stuck. lightly tap each offending carb and see if fuel comes out. If fuel starts to flow, shut off screw, do all carbs the same way. Try to restart bike, if it starts and stalls. You will need to replace all 4 needles and seats. Kawasaki's are notorious for dropping carbs.

i would actually replace the caps and leads on side not working, a bad connection may still spark when not under pressure, then test coil before i think about cdi

first check the oil level it may have a low oil shut off then swap the safety switch from side to side

Ride the bike 20 or so miles on open road. Stop and remove plug to inspect. 'Are they black or white ?


Black =rich white=lean

check to see if any of the rubbers have splits????also i recommend having the carbs balanced.

It obviously sounds like its being starved for fuel, you said that you replaced the pump and the filter, what about the carbs ? has anyone checked them out ?

If the bike has been sitting over the winter and the carbs were not drained or if the fuel wasn't stablized then you might have some dirty carbs, you can try draining the float bowls and then adding fresh fuel see if that helps, if not you'll likely have to pull your carbs and clean then. Todays fuel doesn't las that long before it goes bad.

Check your plugs. If all four are sparking then your carbs are out of sync. They will need to be re-balanced.

If you are capabable in doing this job your self, you will need a screwdriver that fits your adjuster screws and a CarbTune Carb balancer.
Remove your tank and airbox.
You should see the flaps inside your carbs. These should open when you move your throttle.
Start on the outside carbs to get them balanced with the 2 centre ones.
To start, unscrew the adjusters all the way out. then screw them in until the 2 outer carbs move at the same time as the inner 2 carbs
Once this is done then adjust the centre balancer to syncronise the 2 left hand carbs to the 2 right hand carbs.
Now if you have done this correctly, all four carbs should open at the exact same time.
If you have a Carbtune balancer, remove the plugs from the top of your inlet manifold and plug in the hoses from the carbtune balancer.
Start the engine and adjust the screws until the weights inside the Carbtune balancer all read the same.
Once done, remove the balancer, replace the plugs into the inlet manifold, refit the airbox and tank and it should run so much better.

If your not 100% confident to unertake this job yourself, take the bike to your local dealer and ask to have the carbs balanced.

i would definatley check for vacuum leaks . Then check the diaphrams in the carbs. Also check to make sure that the float in the carb. It sounds to me like for some reason that cylinder or side of the engine is getting to much fuel and fouling out the plug. Loss of compression would have to be pretty substianal to cause that kind of problem .

Flashing check engine light is missfire, fuel pump probably causing multiple tries to start.Having to build fuel preasure,vac leak on one side of intake probably causing rich/lean condition.Also check back preasure to cat ,Sound like you are moving down right track.Mas air flow would probably set lean code bank1 and lean code bank2

Clean your carbs! Your floats might be sticking open a bit. Plus, all Kawasakis have a simple spring-actuated check valve in the fuel valve. This way, you can disconnect the fuel line without having to block the flow. Fuel could be leaking through the check valve. Your problem most liklely identifies dirty gasoline. Clean out your tank, your carbs, and change your fuel filter.
