crank breathers usually located on top of engine block or ontop of the rocca cover

Swap the coils around the opposite they are now, 2 and 3 to the 1and 4 coil and vice versa. If now 2 or 3 act this way it's the coil, if it's still the 1 and 4 it's a grounding or plug or ignition module. I would start with the flip first and see what you learn. The coils are the same just split into two different firing signals. So that should tell you a lot

Could be a fuse or the ignition switch itself has shorted out. Check the fuses first.

it is probably too wore out to crank the engine. replace brushes and bearings or find a new starter.

sounds like too much fuel due to blocked air filter, rip out air filter and try again. If not that, you need to determine if electrical under load so take to a rolling road for quick sort out. Fuel problem happens to me in heavy rain as rain down tank soaks air filter paper.

the #should be right behind the front forks on frame

check the ignition key switch is working , might have to dismantle it and make sure its making connections where it should !

Pull the spark plugs and see if they have a black sooty coating. Sounds like a too rich condition.

Your local Kawasaki dealer will have that information

Prob bad plugs, or carbs need cleaning. Timing not usually adjustable..

It sounds like something may have shorted, come loose, or burned out.Tracing where this is will take time and a multimeter to test all connections.

fast change your spark coil & check oscilation circuit volt, puls output check.

Sounds to me like you may have an air leak. Inlet manifold & vacuum pipes are quite common. Hope this helps

Check the float level in the carb. If the fuel level is too high it can flood the cylinder.

2 and 3 run off the same coil which sounds suspiciously like a coil failing.
What does the dealer do to make it run for a day? like putting new plugs in


If the carbs are not flooding and have beeen properly jetted they shouldnt cause a problem.
30 year old bikes dont often have genuine mufflers on them, so they need jetting to suit
If the carbs are standard I wouldnt consider changing them.
Standard carbs work best with a standard air box and filter.
Make sure the fuel tap is working correctly(no flow unless the engine is running) in case its sucking fuel down the vac line.

the float is probly stuck-need to take off the wells where its located--get a clymer manual for details--needs cleanin--actually any ricebike book shows u the procedure
