This is a Kawasaki KMX200
The engine was stripped,new crankseals new piston and rings,all gaskets are new ,power valves are spot less carb was stripped and cleaned ,new air jet cause old one was to big ,float height is now with in tolerance 21mm-23mm.Reeds and block ok cant see any sign of cracks on the inlet rubbers and air cleaner is new.
checked the petrol in the bowl all ok and from what i can tell choke is working ok aswell.
sometimes does not always slow down from 3k rpm quick either when you shut the throttle off and when it does hit idle it cuts out.Air jet screw is set at 1/1/2 turns out tried it in various positions.
the way it cuts out would seem to be electrical rather than a fuel prob checked kill switch aswell thats ok and side stand switch in fact anything i an think of.
