Will not start cold and no compresion - 2005 kawasaki KX 250 F

sounds like compresion going down when warms up

This saw may have reed valves, most times turning them over is good enough.

I have a riding mower that is similarly stubborn; try this which works for me: - Full choke for one cycle - No choke but full throttle for the next try; it works for me/it.

hi, coud well be a compresion problem, when the bike is started will it tick over or does it just peter away and stop if you remove your hand from the throttle? recheck the valve clearances, have they been adjusted with the engine on he correct stroke? when the cam lobes are facing down the valve clearenes should be set with the engine on tdc, and cold, it is always best to have a slightly larger clearence to alow for expansion , good luck paul

The cam chain probably slipped a tooth or more

i would get a compresion check .because it sounds like the head gasket is too thick, lowering the compresion would give the same results.but as its a simple check its the cheapest way to start.....

If it is cold where you live and this a cold start situation it could be a glow plug or glow plug relay problem.

The fact that it needed water and you know have you no fire on a cylinder means you prabably blew a head gasket. Does it blow out steam when you start it from cold now. You will need to check compression on all cylinders and do a chemical block test for fuel in the coolant first in order to rule this out or in.

leak in the compession /broken cilinder head to cooling
(compresion )/thermostad thad regular the teperatuur
radiator not clean insite corrosie from cooling liquid

Check for compresion on cylinders, check for fuel pump pressure.
