SOURCE: 1982 Honda Magna VF750 won't start.

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.

SOURCE: Ignition problem with CB750K Honda

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!!!
Good luck

1986 Honda CR80 quit running

C A R B U R E T O R .. have a qualified professional take a look at it....

your bike only needs THREE things to run,,(assuming the insides are good),,
1. A timed spark
2. Adequate compression
3. Proper fuel/air ratio

Start with one... eliminate one at a time until you find out which one is NOT happening!! (This is how a professional would trouble shoot your bike)!

When I am riding in any gear at around 5k rpms and roll off the throttle my bike misfires. Is this a timing issue? Is there a way to adjust it other than the screw on the bottom of the carb?

Your problem hopefully is simple to fix. Put the motor to top dead center on the compression stroke. Check the valve tolerances , make sure the exhaust is not too tight.
cold IN 0.10 mm (.004")
EX 0.10 mm (.004")
Also replace the spark plug cap and the spark plug. Some times popping or backfiring is caused by leaking exhaust gaskets from the head to the head pipe and some times the gasket between the head pipe and the muffler. If the valve adjustment, plug, and plug cap do not work, try the exhaust gaskets.

Not running on #3 cyl' on my 1982 gs550

Not likely valve timing if it will run, cams are one piece so if one is right all are right. Have you checked compression with a gauge, or just by feel? Try swapping the sparkplug wire with the #1 cylinder and see if the dead cylinder moves with the wire. Also try moving the spark plug to another cylinder and see if the dead cylinder moves with it. If the compression is indeed good, the problem will be with the spark plug/ wire, or in the carb, these are the only things that can kill a single cylinder. The coils run a pair of cylinders so a bad coil would put out 2 cylinders at the same time. Start with the spark plug, I have seen a perfectly good looking plug, that would fire whun held to the head, but would not fire in the cylinder.
