Wits end.

Postby support4pc » Mon Sep 21, 2015 6:59 pm



my 1984 GL1200A Trike is testing my resolve. I started having issues with the engine seeming to loose power, stumbling, running on few cylinders, etc a few months ago. I have since had the carbs rebuilt, replaced spark plugs, replaced coils and wires, replaced fuel filter, air filter, checked and blew out lines in fuel tank (there was some discoloration but not a lot of things floating around inside). Yet it still continues to do it, it will start with a miss and hesitation and build to the point it will just stop running, after it first starts if I give it full throttle it will hesitate and then take off but as soon as I let off the throttle its back to missing. This is a California bike so there is a lot of extra "stuff" tat might contribute to this but I just don't know where to start and there are NO good Gold Wing mechanics locally.

There may still be a spark problem.A bad/corroded ground feeding the ignition module,corroded connections at the 4 wire pulse coil plug or low voltage feeding the coils.
Spark,fuel mixture,compression...

Thanks for the heads up, I will try and track things down, I did run a compression check recently (9/12/155, compression check, cyl 1 = 158, 3 = 163, 2 = 165, 4 = 157)

Compression is fine - I would be looking for fuel or electrical.

Carbs -even if you have done them yourself - I have found that a second cleaning - sometimes can dislodge some miniscule particle that stops things working properly. I would not discount electrical - but it does sound fuel related. I would check and recheck all your electrical connections - starting by confirming spark to all cylinders.

A big thanks to everyone! I found the ground cable was incorrectly installed onto the bolt hanging the motor instead of the factory location, as such the bolt could not be tightened on the ground cable and the point the cable contacted the engine case was actually causing electrolysis and eating away the case, secondarily the repeated loss of continuity and resulting engine skipping caused severe loading of the plugs resulting in a thick reddish brown buildup on them. so far everything seems much better since relocating the ground cable. :D
