Having a problem bike seems to run great except for low gas mileage so i was checking spark plugs and found out only 3 cylinders firing. Changed spark plug cords still not firing any idea?

... Howdy ... Need More Info ... Is There Any Spark ??? Is The Plug Fouled With Fuel ??? Have You Tried A Compression Test On Cylinders ??? ... Happy Trails ...

My "lost #1 cylinder was caused by a plugged pilot circuit, not bad spark.

Had the bike apart got to the coils seems that there might be a problem there. Unfortunately the Honda service manual doesn't tell me what reading
i am meant to get. Did test on pulse generator like manual says and getting bad reading is that because the coil is faulty? It is the #3 cylinder. Sorry if this sound amateur-ish not very mechanical minded learning as i go.

Thanks
Rick
