Hi, Nick if you have changed your fuel delivery system, air filter size or flow rate, mufflers or exhaust system or a significant change in altitude your carburetors need re-tuning and if your fuel system (gas tank, filters, fuel valve and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. You engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" your not getting enough fuel.
1. Closed to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. Wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark gray, the engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.

jet size and exhaust muffler are not connected
failing at high rpms indicates a problem coil or capacitor or failing ignition control module
if it has points or cdi ignition it could be from worn shaft that is wobbling at speed causing the miss

Hi, Brandon nice novella, it could be a funky power valve and they are moderatley easy to clean/repair and you will need the free manual provided below as for a gasket/o-ring you may be able to reuse the old one if you are careful removing it, worse case scenario you can always make a gasket out a cereal box and use high temp silicone for more information about your question and valuable "FREE" downloads that you will need please click on the blue links below.

Check the timing it should be set at top dead center or a hair before top dead center, the other issue could be it's not pulling fuel which would mean it needs a good carb cleaning

Hi, Anonymous 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.

Could be the power valve is dirty or blocked from operating. May be a carburetor problem too. Has the carb been cleaned lately?

Hi, I am confused, your problem question banner shows the year as 2003 for your Kwaka. Vin number is normally for the frame/chassis. If you look around the engine you should see a stamped/etched alpha numeric code. If you call Kawasaki they should be able to tell you the details regarding this code.

Hi, Anonymous you need to locate the fuel flow origin first to isolate the problem area otherwise the usual suspects are:
1. Fuel tank empty.
2. Fuel cap or fuel tank not venting properly.
3. Fuel filter clogged with rust or dirt.
4. Fuel valve not in the on or reserve position.
5. Vacuum line to fuel valve cracked, broken, pinched, or missing.
6. Fuel valve/petcock clogged or diaphragm cracked, cut or torn.
7. Fuel line from the fuel valve to the carburetor or fuel pump clogged, cracked, pinched, bent, broken, or missing.
8. Fuel pump not working.
9. Fuel line touching cylinder or head causing fuel to boil and vapor lock, repair by rerouting and wrapping line with convoluted tubing.
10. Carburetor inlet clogged.
11. Carburetor float or needle and seat stuck.
12. Carburetor not venting properly overflow line or bowl fitting clogged, pinched, or bent.
