76 GL1000 weird firing order

Postby D2D » Fri Dec 30, 2011 12:15 pm



Just picked up another old wing this week and when I got her home I discovered that the plug wires are switched around so you have #1 plug wire on #3 cylinder, #2 plug wire on #4 cylinder and visa-versa #3 on 1 and #4 on 2 .. and the bike fires right up and runs like a top as it was demonstrated as a running bike before I purchased. I followed wiring from the coils to the points and find everything in order .. what am I missing here?

The machine doesn't care as long as each coil goes to the correct cylinders.they both spark at the same time.one on compression,one on exhaust ( wasted spark)

Yep, you can fix it and it will run just the same. So if you are anil like me then that is what you'll do.

The GL1000's fire two cylinders at a time even though only one cylinder needs the spark. One spark is literally wasted. It does this because there are only two sets of points, four cylinders and no distributor.
