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

Should be 2-3 screws on the side of the tank plastics undernieth the decals.

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

sounds like the rings are fried and needs a new piston and rings.. for an 80 there about 110 bucks for the whole kit

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.

clutch plates are shot and probably the springs too

This sounds like the crankshaft seal is leaking

that would be a good reason it wont fit

could be the float , clean carb again . if it was me id check the compression , easy stuff first . then check the spark output to know if your getting weak spark after its warmed up . the service manual explains how to check the electrical system.

start by checking your oil level

You have to adjust your idle screw on the side of the motor ...it should be by your carb. Turn your bike on and then turn that screw to the left until your motor calms down and has the correct idle speed.

Does it have a pinch bolt? If so undo and remove the pinch bolt, if the lever doesn't slide off you will need to pry the pinch part of the lever apart. It should then slide off. If it is worn it will hang loose, you will need a new lever, also check the splines on the shaft.

Service your carb.I think you will find your pilot jet is blocked.

If your bike has shift indexers they could be out of adjustment.

i got kx80 and dont no the year cud u help me frame kx080L-004594 engine kx080EE049741

check and make sure choke is opening all the way,if it is only opening part way could explain why you don't need to use choke at all to start and then at higher rpm's it is not getting enough air causing it to basically choke it self out.

Release arm in engine is broke.

clean carb and check jets

try putting some pb blaster around your shifter shaft or check to see if the shaft or shifter is stripped

it runs but sputters.that can be 2 things.First idd your sparkplug cap has had it (get a new 1 from the parts store)2nd it could be that your getting to much fuel in top end of your revband.easy to check just run your bike a few min with a new sparkplug and look at the color.Wite is not enough fuel.Brown is perfect mix.black is to much oil and if black and wet its to much fuel.try this test and maybe you'll find it
