smell burnt rubber and missfire on 84 gl1200i

Postby toughlife200700 » Sun Jun 01, 2014 12:19 pm



Was riding yesterday and bike was doing great then all of a sudden I got a miss fire that wouldn't go away. At the same time I started smelling a burnt rubber smell and popping in exhaust. When the rpm droped under 1200 I got a rattle or knocking sound out of the engine. Brought it home and parked as fast as I could. It used a lot of gas on the way home and it felt like it was running very hot also. I ordered 2 new timing belts and I am going to replace them before I take off on it again. Was wondering if this sounded like any other problem. Also going to flush the cooling system and replace the radiator hoses while I've got it apart. It's not been running a smoothly as most goldwings sense I bought it at Christmas. If I pull the choke about half way it smooths out wonderfully. I was wondering if a bad timing belt could have caused that problem too if it had jumped one tooth? Thanks for the responses in advance. It a 84 gl1200i

That sounds very much like a broken timing belt, and I suspect that you are going to need to do a fair bit more work than just replace timing belts, unfortunately. Hopefully the engine isn't destroyed.

I hope it's not. It would smooth out every one in a while but then it would start again. Only went about 4 miles after it started. Then shut it off. Not going to even try to start it back up until I get the timing belts on.

OK so the timing belts were not broke. The bike is still in time. I went ahead and replaced the timing belts seeing as I was that far into it. The old ones were a little stiff but still good. Still got the misfire. Still got the pinging at 1200 rpm and below and it still will not idle. So I need some input. Please help. All you can think of.

Did you figure out where the burning rubber smell came from?

Next thing I would check is the compression on all four cylinders.

No have not figured out where the burnt rubber smell came from. No wires are burnt the tires have no show of anything rubbing and all the rubber hoses are fine. The only thing I can figure is it might be a bad igniter. But if one side burnt out would it cause a smell like that? Going to check compression on all 4 soon as I get back in. Just don't know where to go from here.

It sounds like you have a carb problem, dirt in the jets or slide or float sticking. Maybe try some carb cleaner, you might have to take them apart.

Check the pulse generator,at the rear of the engine. You'll get these symptoms if it has a bad bearing,on the PG.
Also,check the sparkplugs,to see if one,or more is loose.It could cause the misfire,as well as the burned rubber smell(plug boots melting).

I can't fix it,if it ain't broke...you want me to break it,first ???

Give me a Goldwing,...or give me Viagra,cuz either way, I'm gonna ride !

Are you blowing your dog bone fuse..??

I had an 84 and my bike would back fire and die on turns. Ended up being a burnt wire under right fairing pocket, fixed wire never had another problem.

Can we assume you have checked the wiring plug (with three yellow wires) next to the battery ??? If they are burnt up most folks repair it by simply crimping on a good wire splice... Make sure you have good clean cooper wire prior... If it too shows sign of being burnt ya might have to splice in a length of good 12 gauge wire to make up for the bad part... On mine, I just went down near the engine case and ran new wire all the way up to the regulator... Use a good water proof heat shrink on the connections... If you don't have any on hand, a decent boating store should be able to fix ya right up...

Using wire crimps to fix a burned stator connector is just delaying the inevitable. The best way to fix this problem is to actually solder the connections, then wrap in heat-shrink tubing. Soldering keeps oxygen out of the joint, which means no oxidation. Crimping the connections still allows oxygen in, which means with the heat of current flowing causing repeated expansion, it will eventually oxidize and fail again.

Ya missed the part about using "water proof heat shrink"... It has hot melt glue on the inside of the heat shrink... No air or water can ever reach the crimp... It is as air tight as the orinal wire is, maybe even more so...

Could it be a bad ignition coil ??

Don't know I didn't get to check compression but I did check all the wires. They all looked fine. I was wondering the same thing. They all spark but one looks like it's a whiter spark that the other 3. The spark a bluish color. Could that be the problem?

A blue spark is preferred over a yellow. It's hotter.
