Front end noise louder(revisited)

Post by Markpenn »

Just got back from a 4,500 trip and noise VERY distinct between between 2,000 and 2,700 rpms, even with helmet on. Very noticeable in lower gears slower traffic. Bike runs fine, but noise very annoying, especially for a gold wing!,Would like some input/advice. (Early post) Short bio, I'm not new to gold wings and have been fortunate to have had four 1500's, but new to a 2010 (1800), a gen 3 with 30k miles. I just purchased it about two months ago. I have put about 1,200 miles on it.(now 5,700) My routine: start it up and let it warm up at idle. Put helmet on and off we go. Now for the noise issue. I decided to change the oil the other day and started her up to warm up the oil, etc. I increased the rpm after the warm up period to get the oil little hotter. Since I wasn't wearing my helmet I could hear the engine in its natural state. While revving it up and at approximately 2,000 rpm I could hear a distinct noise that sounds like a rattling tapping noise. It sounds like the noise is coming from the left very front lower side. Not a real loud and destructive noise, but enough to get your attention. The bike has an after market chrome timing belt cover and lower cowl. My first thought it was the after market cover maybe misaligned causing belts to rub it. Later I was told the 1800's have timing chains(?), not belts like the 1500's.
I also thought maybe the after market belly pan may be causing or resonating a sound effect, so I removed it. Anyway revving it up and at 2k the noise starts and continues up through the rpms, but starts to fade at approximately 2,700. However the engine is getting louder too, so It's hard for me to pin point the noise and able to work the throttle at the same time. After changing the oil the sound is still there. Note: recap and being redundant, after last two week ride noise very distinct between 2,000 and 2,700 rpm
Any input would be much appreciated and thanks in advance.

A recording of the sound would help. Take a video of it, post it on YouTube and post the link here.

To verify if it is cause from aftermarket stuff, remove it all and see if the noise can be reproduced.

How about what else will make it change?
Pulling in the clutch?
putting it in gear?
Loading down the alternator by turning on the high beams, heated grips, seat heater, radio etc.

Noise can travel and you say front end but it could really be from lots of places.

Maybe buy a cheap stethoscope to help narrow it down and then see if we can come up with a better diagnose
I'm Closterphobic so I ride a motorcycle :lol:
