snapping noise

Postby bubbzy93 » Mon May 13, 2013 2:52 pm



I am wondering if anyone has experienced this, I have a 1993 gl 1500, if I sit on the bike and bounce the rear suspention, I get a kinda snapping sound, not a real heavy sound , but the best way I can descibe it is, if the rubber cushions for the center stand ( the ones that cushion it from the frame when it is in stowed posistion ) were missing, and you grabbed the center stand, pulled on it and let it snap back in the stowed posistion, the sound that would make is kind of what I hear, It sounds like its in the rear suspension area, I have removed the seat and bounced the bike, and the sound is still there, but its hard to find when you have to balance the thing , bounce it, AND try and figure out what it is, I bought this bike last fall, and it has always done it ( since I've had it ) I tried asking the fellow I bought it from, but he has moved away. Any body else have a simmilar experience?

No funny noises on any of mine like that but let's narrow it down a bit...
I hope you can lock the rear brake down and bounce it again to eliminate that part(caliper mounts).
Keep the rear wheel locked to avoid any rolling movement.
Moving or flexing parts.......
Swingarm bearings
Loose axle/nut
pivot pins in the shocks.
Universal joint.....Roll the bike 8" and try it again...This will turn the "u" joint.

Next...using nothing but the best diagnostic tools...(voice recorder,I-Pod,I-phone,etc)
tape it close to each pivot/mount point and make it click....Play it back to closer locate the noise.

Get someone to stick a rubber tube in their ear and use it like a stethoscope to locate the noise.

Inspection of each joint for excessive play,like the bottom of the shock mount missing the rubber bushing or such things...

A visual inspection of components will often reveal the source of the problem with things mechanical.

Remove the bags and give it a good look see.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

Making the sound under all tries indicates it's the shock mount.Either one,and either end.
Get a eyeball on it and pry with a screwdriver.

Okay, so I finaly had some time to check out this noise, I removed both side bags, which, by the way was very easy ( I've been tearing cars apart for 30 years, car companies could learn alot but seeing how this is made and put together, but that's a different story). I closely inspected all mounting points and bushings for wear and looseness, all looks good, I jump on and bounce the bike on the rear suspension as hard as I can, "snap, snap, snap" I call my wife to the garage, and ask her to watch the shock mounts carefully to see if the move or flex as I bounce the bike, nope, all looks secure. then I ask her to place her hand on the top part of the left rear shock, and I bounce the bike slowly at first, then harder till it snaps, she says she can "feel" something here. Now this bike has dual rear air shocks, so, I pull down the rubber on the bottom of the shock and ask her to place her fingers on the botton part of the shaft, I bounce, till it snaps, yes, she says, I feel it. Okay..... I go and get the binder that this guy made for this bike, I remember reading something in here about the pressure settings. He had written, shock air pressure, single 2.5, double 3.5 -4.0 loaded 4.5-5.0, hmmm, I know I haven't put that much in, cause when I test drove it ( with both of us on it ) he set it to 1.1 ... So I set the pressure to 2.5, bounce the bike as hard as I can ... wala ... no snap.... so.... I guess I never had enough air in the shocks, and was bottoming the shock out .... I know what you are all thinking, and you are right, I'm a dumb ass for not reading up more on the air suspension, I set the tire pressures, set the shock pressure to 3.5, and we rode into work this morning ... nice and smooth... and no snap... sorry I didn't take any pictures, but I didn't really see the need for it.....sigh.... I feel better now, although I do have a well placed palm print on my forehead --- DUH!
