I have a 1981 CB750C that has not been started for several years. I don't believe it was serviced to be stored, it was just parked in the garage.

I cleaned the carbs, changed oil, installed coil pack and now when I try to start it only one cylender fires.

Any suggestions will be greatly appreciated.

Are you getting Spark off of your plug whose cylinder isnt firing?

 

Yes I have spark to all cylinders. I replaced coils, and plugs. I haven't changed wires yet because I haven't located any yet. Imay need to make up a setmyself if I can find components like boots.

Thanks for response it is appreciated.

 

First off, I'm glad you have the very same 750 I have.
Did you change out all the old gas? You may need to
use starter fluid spray before it starts.
Do you happen to know how many quarts of oil are used
when you change the engine oil? Ken
