1984 Goldwing Interstate

Postby Wingrider63 » Mon Jul 12, 2010 7:59 pm



I'm new to forums and a new Goldwing owner. So excuse me if I don't get the ettiquette right. I have a tired Interstate. 53,000miles. It starts easily. Runs strong but... yeah, there's a but....it has a noise, a rattle. Not a knock. Sounds like galluping marbles, kinda. Sometimes it sounds like its coming from the front and sometimes like the back of the engine. I'm a little hearing challenged. Sometimes I think it sounds chain like. I had a mechanic who works on old bikes take a listen. He wasn't sure but thought it sounded like a worn ball bearing and race? on the crank. He didn't say to not ride it. What do you all think? Whats the noise and would you ride? Are parts and rebuild kits avaiable?

When does it make the noise? Low speed, high speed, engine speed, throttle position, etc.?

It's pretty much constant at all speeds. It may get louder going down the road, but with all the road noise I can't tell. If I rev it up, it sounds like background. You can hear that nice precision machine sound of the engine running behind the noise. If the noise wasn't there it would sound sweet.

Does the frequency of the knock increase as the bike speed increases?

If you get up to 30 or 40 mph, then pull the clutch in and let the engine go to idle (or even shut the engine off), does the noise continue?

I took the bike out tonight and did the 40 mph clutch pull and the engine dropped to idle. I didn't really hear the noise due to road noise and wind. I pulled over. It was still there. I thought that after about 3 miles it might have been slightly louder(margainally). It has a clattery sound, less like marbles than I originally thought and wrote. As I took off again and increased speed and power the noise didn't get louder, just faster. It was eventually drown out by the throaty sound of the exhaust and the road noise again. Now I noted something new. I hadn't ridden this bike in the dark before, so I noticed that the headlight dimmed down with use of the brakes-front and back individually. Is it possible that the alternator is the source of the noise? Or is this just another GL 1200 characteristic? The last Goldwing I owner before this one was a '76 GL1000 and I don't remember the way the engine sounded. I know the headlight never dimmed when I hot the brakes. I sold that bike in 1984 and just started riding again in the last couple of months-when I bought this bike so essentially I am a greenhorn again :lol:

The idea is to isolate the noise to either the engine, or to the drivetrain/wheels. So you need to ride until you do hear the noise, then remove one of those items (engine) by declutching, and optionally shutting the engine off. If the noise disappears, you know it's the engine. If the noise continues, you know it's the drivetrain or wheels.

A lot of these old bikes will dim their headlamps with the brakes applied. Pulling the brakes lights up your taillamp, which draws an extra 54 watts from your electrical system. That's a lot of power when the total output of the stator is only 300 watts - and it has to drive everything on your bike, including charging the battery. And that 300 output is a) at and above about 3,000 rpm only, and b) when the bike was new from the factory.

You can fix this by installing high-brightness LED bulbs in your taillight.

The noise I have in my 84 Interstate comes from the back of the engine. It almost sounds like you have discribed. The noise in mine is more pronounce at idel and is less heard going down the road. I have looked at inturnal pictures and I have thought it might be the starter chain or drive chain. I have accesss to a blown 1200, but I have not had the time to open it up. I am not scared of the noise, yet, but my biggest problem is the gas it uses! Maybe I am too use to my 83 V65, but I only get about 70 miles to a tank of gas when rideing back and forth to work. Most of it is in town driving. I know the bike weighs alot more. I have changed the plugs, but haven't set the carbs yet or checked the timing. It also feels like it has a lack of power on take off. Once I can open up the blown engine I can see what is what on the back side of the engine. Once I see, I'll post it up for you. Happy riding, and Ride Hard and Ride Free.
How many times do I have to tell ya,,, The right tool for the right job!

Thanks for the input. My noise sounds like it's in the front then in the back and, like yours, I'm suspicious ot the chains. I'm going to remove the lower fairing today and see if I can further isolate the noise. After I get the lower off I'm going to inspect the timing belt. I used to go through them for no good reason when I ran a 76 Goldwing. I'll post when I get a handle on this. Feel free to comment as you zero in on the noise. :)
