Hey Guys
New guy here and thank you for everything you have already done in other topics even before I joined to the forum. I have a 1200 Goldwing 86 and there’s this tapping maybe rattling but more like and accelerated tapping that follows the same rpm of the engine even in neutral. Since to come from the center of the engine. I just got a stethoscope and will try to find location of sound but I will also check the clearance with the gauge at the collar in the valve case as per describe in clymer. I tried to find a similar case to mine in the website but not his yet, does this sound familiar to any of you? Bike runs great(except for the noise)! Thank you!

Isolating the position source of the noise is a good start.

Did it just start the noise?

Hello Alas,
Welcome to the forum,

just curious, your IP address "seems to" indicate you are from around the Buffalo, NY area,
is that even close? Notice you are using a T-Mobile internet connection.

Actually I’m visiting family in west Chazy but I live down in key west FL.
The bike came with the noise, it sat for a couple of years. I thought first could it be a stuck valve but today I was spinning the crankshaft by hand while I was changing the timing belts so I took the covers off and all eight valves where moving.

The hydraulic adjusters can collapse and take a long time to pump back up. How long did you run the engine? If the noise seems to radiate from the right or left valve cover it might just take some run time?????

I bought a '94SE that had sat up for 3 years at least.....
the lifters were all flat on the valves that were compressed....

I dumped in 4oz of Sea Foam in the oil, and rode it for a while until they finally turned loose and started working again. then all the "Clattering noises" went away.

Update. And thank you guys once more.
Using stethoscope seems the noise is coming from the section were the U joint is, it’s louder there but it echoes all the way to the center of the engine. I just change the timing belts and I hear a little soft slapping so I opened up again and tightened more and still up to clymers specs 3 to 5mm slack. I wonder if it will just go away at some point. Thank you

Not unheard of for a uj to go just rare
Bryan,
Might not have read his original post good enough. U-joint would not make noise in neutral or be tied directly to engine RPM. In gear running with the clutch pulled in does it still make noise?

U Joint won’t make noise in neutral??! Ok that makes completely sense because the tapping accelerate with throttle in neutral too! Thank you. I’m going back to the drawing board now.

Did you check for possible exhaust leak where the header and head meet?

There’s a copper gasket that goes between the header pipe and the head,,might check the header bolt for being tight.
