1982 Goldwing noise at idle

Post by lbwegner1 »



I have a 1982 Goldwing I bought with a noise at idle. Maybe was a mistake, but it seemed to run good at higher rpm. So what might make noise at idle, but not seem to at speed? I don't remember the miles, it's in the garage. Where do I start to try to fix this? I live in Minnesota, so riding it now is out of the question. Thanks for any help.

My good man.....(errr maybe?) there are a number of noises that could cause low rpm noise, that may disappear at higher rpm's. A bearing going bad on the water pump, at higher speeds it may just go away especially if it is marginally going bad. That is but 1 of a number of issues and to be of better help to you, it would help us if you could describe the noise better. Also using a mechanic's stethoscope to listen to different locations say the front timing belt cover, under the cover where the water pump is, the head covers, and possibly the rear of the engine on both sides may help to locate the noise better. On the 82 the valve lash is adjustable and could cause a noise if it is badly out of spec. I surely wished I had an answer for you, but, it is nearly impossible to guess what your issue could even be.

Thank you for your thoughts. That does give my some places to listen to and think about. I appreciate your time.

I think it sounds like a loose chain drive, a rattle maybe.

There is a Primary Drive chain that I think goes to the transmission drive gear and an oil pump drive chain. There is also a Sprag Clutch (starter clutch) drive chain that is only active during starting. If low speed the chain slack may be causing the noise on the primary drive or the oil pump drive and would definately disappear at higher RPMs due to the fact its spinning faster and the slack (usually from being stretched over time which happens to almost all chains) is almost non-existent at higher RPM. The primary drive chain is layered up and stronger which makes me believe (rightly or wrongly) it probably is the oil pump chain cause it looks more like a double gear chain drive. The oil pump is at the bottom of the engine so if you put it on the center stand freeing the rear wheel, and start it, put it in gear, you should be able to hear it with a stethoscope rather clearly. Just be careful to not knock it backwards and have the drive wheel hit the floor. Bad things will happen. If you have a swingarm lift that would be safer and raise it higher than the center stand would. OR have someone sit on it leaning forward to prevent the wheel from engaging the floor may help too. There is another option it could be but it is rather in depth and is inside the back of the engine.

EDIT: I found this on another site;
The chain noise is normal at low idle. If it does not go away under load, it would be something else.
This was an answer to a chain slap/noise at the rear of the engine where the primary drive is located. Maybe the issue is moot?

Most likely and the usual common cause is the carbs are out of sync, which causes uneven pressure on the pistons, which is transferred into the primary chain slapping noise on the case. There have been many posts on this over the years on the different forums. 4 cylinders and 4 carbs takes precise tuning and when done properly, they pur at idle.
There are many steps to follow on syncing the carbs to get them balanced properly to have no noise, all outlined in the service manual.

Thank you both. When I bought this, the seller mentioned the carbs might need work. Thanks

Sounds like a perfect time to rebuild and bench sync the carb's. Bench sync is ok and can start and run the bike but to dial it in perfectly you would need a real sync matching all vacuum's as closely as possible. I just bought a 4 gauge set to do that to mine. Mine were rebuilt by Pete Boody, (actually his son) who recently passed away. He was known as Pistol Pete and his son has decided to shutter the business. Not sure if that's permanent or not. I tried reaching him last month and have gotten no replies.

My bet is a carb synch will clear it up a lot -
If it 'rattles' a little as you add throttle - I think synch is out a little -
That is a challenge on these bikes - but you can get it there with some patience -

The plan is to synch them in the spring and put some miles on the bike. Thanks
:D
