Well that's baffling, Lodle. But welcome to the forum.

That bike has points, right? I think I'd start there.

It's been about 30 years since I had a bike with points and all I can remember is they were a constant source of agony.

Bike looks great, by the way.

if you want to keep it factory keep the points but i would suggest to change it to electronic system not a ton of money to do the upgrade plus probaly get more power out of the old girl

Sounds like loose wiring..or ground..I'd check the coils and all the wires leading to them. double check your timing and valve settings..check the ends of the plug wires might clip off a 1/4 or so to get a new clean end?

Hard to track down intermittent stuff like this

PS...VERY NICE BIKE...my favorite year and color

I think RB is right, check all connections and get a set of ngk plug boots.

Thanks for the reply. The bike has electronic ingnition. With the number 3 cylinder never missing and being closest to the fuel entry port on the manifold, it just makes me wonder if the pressue is low. I am going to change the fuel filters again even though they are not that old, just to make sure something didn't get into them.

When they miss, for how long does it happen? And how are you narrowing it down to the specific cylinders?

That's a very good question.

I have not had a chance to try it today, but yesterday it was the number 1 cylinder and it was from the time I started the bike. I let the engin warm up, then pulled the plug wires from each cylinder. The number 1 cylinder was the only one at the time that when the wire was pulled did not effect the engine. While the engine was running, I would also put one of my extra plugs in the cap to make sure the cylinder was firing. All cylinders were firing. It has happened before that both cylinders 2 and 4 were missing at the same time.

You might try taking the air cleaner cover off and spraying some carb cleaner in the intake when it is missing. If it smooths out, it is probably lack of gas or an air leak somewhere downstream of the air intake. Spraying the carb cleaner around the outside of the carb and intake will help locate an air intake leak. If it smooths out, you've found it.

One problem with pulling off a wire on a Goldwing plug is that the ignition coils are double ended. The secondary coil powers two plugs on opposite ends of the winding. Pulling one wire off can cause misfiring on the opposing plug. Using a spare plug as you did is a better check. What does the color of the plugs look like, is #3 cleaner looking that the other three or are they all light tan?

Buy a can of Sea Foam and add about 3 OZ to a full tankof fuel. Go out and run the hound out of it for a while and then see. Get Sea foam at a local parts store.
