I suspect dirty/plugged carburetor body passages if you have power below and above quarter throttle. If it just stops at quarter throttle and misses from there on out, then I would suspect either the needle jet holder tube or the vacuum diaphragm.

If you have a Canadian model, it could be the fuel primer pump in the float bowl has failed.

Go to Kawasaki.com and print out the parts diagram for your carburetor. Then completely disassemble and clean the carburetor with a first rate non-foaming carburetor cleaner.

Pay particular attention to being sure you remove the pilot air screw (in front of the fuel bowl and likely under a metal plug) and the pilot jet (in front of the main jet, numbered on the diagram but not listed in the parts list itself), and all the main jet and needle jet holder and guide assembly. Also be sure you remove the diaphragm cover and diaphragm and inspect that diaphragm for any cracks or pin holes - any leak and it will just bog out and not perform.

Inspect all the hard parts of the carburetor, then be sure that the body of the carburetor is open and clean in all internal passages.

Good catch, do not run any of these with a dead battery as the battery serves as a limiting capacitor for the alternator, and if bad it can allow the charging system to run so high that it can short out the igniter and in addition can cause the coil to break down from too high a field voltage and cause it to fail.
