Title: On the road and hearing a disturbing sound
Post by: ewryly on July 08, 2019, 11:30:06 PM
I'm in Warren, PA on my way to CO, and when I stopped this evening I noticed a growl or vibration when I rev the engine.  It seems to be coming from the area of the dash. I tried uploading a WAV file, but I wasn't able to.  I'm going to try sharing it through dropbox.  I'm trying to determine how serious this might be.

Have you removed any body panels recently? It sounds like one of the panel's prongs may not be firmly seated into its respective plug.

Also, if you did a recent oil change, check the engine guard under the engine, which at least I had to remove to get a good purchase on the oil filter.

Also check the windshield bolts for tightness (3 lbs. torque setting... a bit tight but not too tight).

Thanks, Harry. I have removed the panels, so I'll check those again.  I tried to stop the sound by holding onto various pieces fairings and the windshield, but nothing seemed to work. I don't have an engine guard.  I'll try again when it is light out.

There's a tiger in your tank.


Am I the only one old enough to remember that advert ?

I've just remembered a really odd vibration I had, I eventually traced it to a satnav charger connector when the satnav was removed. The pronged charge plug was a plastic clip in unit and it was loose enough to make noise at some revs, amplified by the plastic frame.

During the same exercise I found a missing rubber grommet for a side panel, I must have pushed it through when refitting. Now I've put silicon grease on them all to prevent this.

Are those are the grommets you find on the garage floor after you've reinstalled your side panels? :008:

It sounds like angry ants to me....ask Bern-Grt :745:



seriously though, it sounds like a clip is out somewhere, or a screw is missing from the radiator cowling etc. Sorry I can't be more specific

I am beginning to think that is what it is. When I get to Colorado, I'll have week to look it over.

it's only when you wake up to find them on the ceiling above your head, arranged in formation, spelling out the words "WE ARE LEGION" that you really need to worry..... :005:

I think the gas cap can rattle if not properly centered.

Thanks for the suggestion. It sounds more like it is coming from the front and under the noise.

Do you have additional crash bars fitted?  They will connect to the Engine and Frame, so will pick up on the engine vibrations more easily and if there are any loose nuts and bolts, such as the Lightbar Mounting bracket under the Nose then this will rattle.

No crash bars.  Tomorrow I'm hoping to get a chance to spend more time hunting this down, plus I'll have some additional ears to help.

One of my favorite tools is an automotive stethoscope. It has helped me diagnose rattles in my family's old Volvos for years. It really helps pinpoint the source.

I've made it to Breckenridge, CO just fine, and I had my brother listen while I rev'd the engine, and vice versa, and I do think it is likely a panel, but none of the obvious ones.  It also sounds lower once I got a chance to move around and listen to it.  I think a stethoscope--maybe a piece of rubber hose--would help pinpoint it.

If you don't have engine bars you can take the whole front cowling off in one piece in 6 minutes. It's super easy. Will give you a much better look at what's what.

Good luck.

I think that is what I need to do. I seem to recall reading that there are some rally raid instructions to do that, or am I confusing things?

BTW, the sport x-creen spoiler added to the stock screen has been perfect for my 5' 9" self. Thanks
For doing all that research. I've done a few hundred miles at 65 mph on RT 36, and that setup has easily been as good as my VFR.

Check out Juan Brownes steering head bearing video on YouTube. He goes through the steps for taking the fairing off too. It's 1,2,3.

Glad to have helped.

Found the culprit!  After removing the side panels and some of the front ones with no success, I stopped by the shop where I bought the bike, and the service manager took a look with me.  At first, he also thought it was coming from the instrument panel, but on closer examination, it turned out to be the Denali lights.  I had tested the light bar I was using, but it did not occur to me that the lights were also vibrating just enough to make the noise.  It took all of two minutes to tighten them up, and now I am once again undisturbed!!  Thanks for all the suggestions!

Was it not noticeable as you were riding at night with the lights on?

I think it would have been, but I try to avoid riding at night, especially in deer country, and I saw a lot of deer even during the day time. I checked the light bar, but it was tight. What I should have noticed was the change in the sound when I put my hand on the bar. The sound didn't disappear, but it did change a bit. Of course my hearing isn't great, either.
