Some articles I have read suggest removing the stock auto-choke carb and replacing it with a Honda CT70 Carb. Check with a local shop to verify, I do not own either and am just passing along the info.

Another solution suggested by 'OneRide': Try it with the gas cap off. The tank vent might be plugged. Possibly plugged fuel filter. Are you using the choke correctly?

This seems to be a very common problem and no 'one' solution to fix it.

I hope this helps.

Yeah,it starts. I do the same in mine. Or just use a cloth with fuel on it in the back of the carb,as i did before getting the can of spray starting fluid.Btw,if your bike doesnt want to start cold may be a carb problem(lean mixture) or choke not doing its job.

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.

To start with was it fine before you cleaned it? Is any gas over flowing from the carb at any time? Does it start well when cold or hot? Will it take throttle slowly but not quickly? Did you adjust your air screw? These answers will help me determine what is going on. Did you pull the float off? Did you check the choke and make sure reassembly is correct?

Try gravity bleeding. Open bleed nipple and wait for steady dripping. After closing nipple, the lever doesn't have pressure, the cylinder at the lever is defective. It's a go- no go thing. Either it works or it doesn't. good luck

hi, are you saying since you addjusted the valve clearences the bike wont start? re check make sure you had the engine on the correct stroke, remove spark plug, check piston is at tdc, and the cam lobes are facing down, recheck your clearences here, hope this helps/paul

Hi,sounds like a clogged jet, a good carb cleaning should fix your problem.

Sounds like the timing is off.

when you shift to 1st.gear does it clunks or do you hear a noise?

Google Kawasaki and find out. I doubt they have one, you'll probably have to buy a new one.

check for spark with the plug grounded to the head only,
you should see and hear the spark,
if you crank it over without the plug grounded it can build up damaging voltages in the CDI and ignition coil. I guess you have tried a new plug, try with the kill button disconnect

check your intake and exaut vavles that was my problem

I would use any that are compatible with aluminum engines. You can usually get the jug in a premix or you gan mix your self 50/50.

LIGHTLY seat the throttle screw and air screw then turn both screws one and one half turns outward.This is the factory setting.

You might be hitting the rev limiter, if not you have carb problems.Your main jet might be the wrong size if you have a pipe on it. Chaz Moto DC

sounds like your carb float has stuck and letting the fuel overflow, remove float bowl or carb clean check if the float has a leak shake it and you will hear fuel inside , refit and check

the valves are under the camshaft on the top of the head, double overhead cam 4 valve. not sure about the adjustment,

any KawaChem or AmsOil 10w 40

heat and timing issue. check your cylinder for cracks and your piston/rings for damage.
