SOURCE: rough running kawasaki
you need to let it warm up before beating on it. inline 4s are always cranky when cold. another issue could be dirty carbs and clogged carb jets causeing it to run extreemly lean, rev high and die out. pulling 4 carbs isnt "fun" but you could do it in an afternoon.

SOURCE: wont run...
Any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Get a fresh set of stock NGK spark plugs. Clean or replace the air filter. You seem to be pretty thorough in what you have done, but since plugs and filter weren't mentioned I had to ask.
Assuming you are getting air, gas and spark, and the timing is correct then it should run. Right? Not necessarily. Can the bike breathe? If pressure cant get out of the tailpipe the bike won't run. Mufflers can sometimes collapse internally. This restricts the flow of burned gasses. causing backpressure. If nothing goes out of the cylinder then nothing goes in.
Try removing the exhaust pipes. Now see if it will run. Get back to me because I would like to know what you find.

Hi there Dave
I would check Carby setting. Like float levels, Mixture screw setting. These can make the bike run
roughily. Also the spark plugs settings, eg not right gap or heat range or ever reach. One other thing
is vacuum leak eg from a vacuum hose ( this usely makes the bike run rough all the time) Simple way
to test this is use a can of WD 40 & spray over the vacuum hoses & if it stops the problem for a short
time you need to replace the hose or fix the leak. I hope this helps your problem, if not please put up
some more info on what you have done to help you There is many little things that can course is

check that your carbies are synchronised .
i would make sure also that you dont have a faulty HTand HT lead to the saprk plug which may cause the wet plug .
check all electrical first prior to thinking of a valve problem .
try to swap the HT and see if the senario happens on another cylinder . if it does , you know than your HT will be faulty .
try that and see how you go .
