1979 GL 1000

Postby rguyer1 » Wed Aug 19, 2009 8:32 pm



I just recently purchased a 1979 Gold Wing gl1000. Cylinders 1 and 3 are only firing some of the time. As I accelerate they kick in but as my speed levels out they shut down again??? Not even any sound out of the right side of the engine. I've got good spark and did a compression check and all is good. Any help would be greatly appreciated. Ralan rguyer1@yahoo.com

Your carbs need an overhaul by the sound of it. You have fuel starvation.

Get a complete set of parts and the video from here and read all the carb tech tips while you are at it. http://www.randakks.com/

Another possibility is a blockage in the fuel lines; maybe the fuel filter needs changing.

Nope, I'd definitely go with electrical rather than fuel. Cylinders 1 and 3 share the same coil and igniter. A problem with the coil/igniter will affect both cylinders 1 and 3 (or 2 and 4, as the case may be). When you accelerate, more available system voltage will cause enough spark to light the cylinders off. At lower RPM, the lower voltage is not able to overcome the faulty coil/igniter/whatever it is, and the cylinders stop running.

Yeah, you're right. I didn't take enough time to read it properly. :oops: (they also share the same wiring, points, condenser. It could be as simple as a bad connection on the coil)

[size=150] Old Fogey, The first thing I did was rebuilt all 4 carbs with new O-rings and gaskets when I got the bike, a good cleaning of the carbs was necessary when I got hold of it. Been to http://www.randakks.com for all the articles he posted on carbs and parts and read extensively!!! Even took Randall's advice on using real fuel, I found some just outside of town and added a full tank, nedless to say the bike wont run at all now. Will not fire at all... I think I'll go back the corn mash where all subject to use now, at least it was running then...

All yeah, Before I added the real fuel, I bought a carb synchronizer and tuned all 4 carbs perfectly, made it run much worse, cylinders cutting out, smoking like crazy... ??? Now I know what the GL stands for,,, "Good Luck" trying to fix the damn thing!!! What a fu*ked up bike,,, I never own another one...

If you read my last post you'll see I changed my mind on it being fuel. i agree with Admin that it's more likely to be an electrical problem. Your different fuels are not likely to cause it not to fire at all; you would get something if the plugs were sparking.
