Try starting it then pull the plug out right after trying if the plug is wet you have to much fuel and the float is stuck or has a hole in it and it is most likely your problem if you have fire. if it is flooded you can pull out the spark plug and clean it and kick the motor over to get excess gas out of the cylinder try installing it again then start it, does it fire up? if it does it's flooded due to the problem listed above. If it does not start pull plugs out again add a cap of motor oil in the cylinders and if the plugs are dry reinstall plugs and see if it runs, If it does it may have stuck rings the capful of oil will make the rings seat once this happens they rings should loosen up if not and it will not run after you shut it off then you have low compression. This is assuming you know you have a blue spark to the plug and have cleaned and gapped the plug or plugs. If you need more help psot here and reply tothe e-mail you recieved with this. Hope this helps.

I have a 1980 CB750-F Super Sport and I went through this problem once.
After that long time, as MATHEW said, some gunk (gorilla snot) could be formed into the little carburetor's passages.
It will not come out if You don't "soak" the DISSASSEMBLED carburetors (without rubber parts) into carb cleaner for at least 6-8 hours.
After that, You can wash them with thinner, and then go on with compressed air.You'll be surprised with the amount of gunk that remained into the carburetor's bodies!!!
