Start with the basics, do you have spark?
Test the plugs by spinning the engine over with the plugs out but connected and resting against the engine.
Do you have a nice bright spark on each?

Check the choke connection - is it activating the choke fully.

If so check the radiator, take the cap off and check the fluid for any signs of oil.

You could try adjusting your tickover setting up & down as that might help if it's carb related issue.

That I think is all the easy stuff.

After that it's carbs off for a clean out & /or compression tester on the engine. If you have a compression tester to hand then do that after testing the spark plugs anyway.

nope
new bat. not new but clean iridiums and choke was fine :clap


======>>>>> >>> >> > Solution :mic
Thanks for Internet :clap
let me Share what i just did,

1. take all pulgs out, clean them (no need to burn their tips) and do not install
2. Disconnect the main fuel line (goes from tank to carbs)
3. Disconnect the other valve(small) goes out from the fuel tap and close/block it with a small screwdriver or nut(don't let air go in)
4. extra: i also cleaned all plug wires, disconnected from plugtops and clean the end of wire or you can cut 2, 3mm from the end of the wire
5. this is important, while plugtops hanging out of the engine, start your engine 8-10 times :puke
6. install plugs, plugtops, fuel line.. everything..
7. start your engine :hat

after this i found my bike start early in the morning without choke.... it doesn't die, i keep 1min or 2 idle then everything fine
it's like new life in the bike... i think clean plug wires did the trick

cheers!

you mean remove the plugs and remove the caps - start engine 8 - 10 times? now that is to clear excess fuel on the spark plugs chamber?


i'm also having a problem with my hornet, there was a leak on carbs, so cleaned carbs put them back on and started fine, but with small leak,
removed carbs check for leaks used threebond gasket on float bowls install back carbs and started fine, but still with very small leakage

removed carbs for the 3rd time found out that leak is coming from the top, old or previous owner used epoxy to seal leakage, used epoxy and leaks are gone, now install back carbs and bike doesn't start anymore

my bike is now starting, i just need to set the right a/f mixture, i need brown tip on spark plugs, i guess my mixture is too rich

do i turn the a/f screw counter clockwise to let more air in?

Yes, doesn't it work for 2.5 turns out? that is what i have
but my mechanic had a different set up, it was not all same turns out but i set them all 2.5 turns out. i think it may burn more gasoline than mechanic's but it doesn't really matter :D

I am confused. Can you confirm again about mixture screw setting:
- Counter clockwise (loosing out): leaner.
- Clockwise (tighten in): richer.
The internet seems to say the reverse?

I am having problem of misfiring at cold start in morning, I guess it might be rich mixture problem so trying changing the screw setting day by day but till now it is just worse.

what i have done is, clockwise all the way in(DON'T make it too tight, you would break the tip)
then counterclock 2.5 rounds out
thats what i have all 4 carbs

try quality grade of gasoline... like Oct.95 :D

Different models have different settings. Check the workshop manual for your specific model.

I am talking about the 600 of course :angel

My carbs are original (Keihin VP03 or VP05), I guess. Can you please comment?
