noise, a little long
« on: November 28, 2008, 06:54:00 pm »
A while back I posted on the ZG/GTA board asking about a noise my '06 had. I got a few answers but non that would solve the problem. The Noise is like a whistle or a squeel. The sound is engine related and only can be heard when riding and between 1800 to 2500 rpms. I had the dealer look at it and he said that Kawasaki would not do anything about it." it's only a sound" The guy that looked at and rode the bike said there was nothing to worry about. For the record he is a good friend and I worked with him for 3 years after I retired. It has had no effect on the bike in 16000 miles but it' driving me up the wall not knowing.

Best guess I can give is that the balancer shaft adjustment has been...um....adjusted.  Incorrectly.  Did you or someone else adjust it in an attempt to reduce vibrations?      There's a link floating around out there with a good description (with drawings/photos) showing how to adjust it.  If I can find the link, I'll post it up.  Or someone else will come along with it I'm sure...  Mike B / Gig Harbor, WA

When I asked about the noise one of the suggestions was to adjust the balance shaft. I have run it through the entire range to see if it changed anything. Nope! The noise didn't change at all. Now the strange part of the story, it seems to also be temp related, not the engine temp but ambient. No such noise when the temp is above 75-80. Still puzzled, other than that my favorite bike out of 29 owned.

Check the cheap things first.    1. Lube your speedo cable.  2. Check your brake calipers for any drag.  3. Pull in the clutch at speed. Still a noise?  4. Tires can be the cuase of certain noises at certain speeds. But this is usually a howl and not a squeal.  5. Remove the deer whistle that your neighbor secretly installed to drive you crazy.    If this is your first full fairing bike then you will be finding lots of noises that used to "not" exist.  A Whistle or squeal (as you described) is usually the balancer shaft, speedo cable/hub or tire noise at speed. Although if you have an unusual edge to the fairing/windshield ie: something with a hole/split in it, this too could be cause to your noise.    Make sure you have all the fairing screws in place and definitely check the big loose nut holding the handlebars as this is almost always the reason we jump to conclusions and do dumb things in the first place.     Best of luck.    AKA "2linby" That's 2-lin-by folks!  Northwest Area Director  COG #5539  AMA #927779  IBA #15034  TEAM OREGON MC Instructor    http://community.webshots.com/user/2linby  http://tinyurl.com/njas8 (IBA BunBurner Gold Trip)  http://tinyurl.com/lwelx (Alaska trip)

   I think you may be onto something here. It may be vibration related and what you are hearing is a high frequency buzz.  Given the newness of your ride, a common high frequency noise maker is the plastic cover around the ignition switch. Put you fingers on it to dampen it when you hear the sound.     If not it, then it is time to do some detective work and start narrowing down culprits. Can you hear it when the bike is not moving? If so, this will rule out many things. Remember that a bike's fairing will make a sound seem to be coming from places other than the source.     --  Steve Smith, COG #3184  COG Northeast Area Director, AMA, MSF RC  (somewhere in south central CT)     If you're not living on the edge, you're taking up too much space.

Try leaving the speedo cable innards out of the sheath just to see if it is in that system.  ----------------------------------  I will answer any question.  It is up to you to figure out if I should have.    <p align="left">My Photos<br

My '05 has a whistle too, at exactly 3600-3800 RPMs, but not when it's cold. Real noticeable on the bike, but not if you're next to it. I think it's located right at the carbs. Heck now instead of a dummy light I shift by my dummy sound.  Wait that didn't sound right...    I quit looking for it months ago, but I hope you find yours. Mine is only a brief whistle as I go up through each gear, yours sounds like it coult get bothersome.

If it only happens when moving I would not think it is Engine related.  I would be thinking drive train, wheel bearings, speedo, tires or something else only in play when moving,  Respectfully Yours!  Wess Heavner  COG #8010 CDA #0239

The noise does go away when the rpm's drop and the bike is still moving but you can hear the noise when the engine is running while not moving but not as loud. Thanks for all the suggestions, keep them coming, you might help me keep some what sane.  COG # 8216

IIRC this is a gremlin mating whistle.

My 98 has a whine whisle also.  It drives me crazy and I haven't been able to find or fix it. I just tell people it's the turbocharger whining

If it were my bike, I'd be giving serious consideration to pulling the valve cover, and checking out the cam chain...since it's RPM related, the cam is the easiest accessed area where it could possibly happen. While at it, I'd go ahead and adjust the valves.    Sahagan

Sahagan: "If it were my bike, I'd be giving serious consideration to pulling the valve cover, and checking out the cam chain...since it's RPM related, the cam is the easiest accessed area where it could possibly happen. While at it, I'd go ahead and adjust the valves."    I did adjust the valves a few months ago and while at it did look the cam chain over. Didn't find anything that looked strange.  Is it possible there could be a engine related air leak that could occur at the 1800 to 2800 rpm range?? The sound seems to sound like a loud air whistle. The fact that it is rpm related and only during the 1800-2800 rpm range is what is puzzling. Going up through rpms or going down through the rpm range makes no difference. Same noise steady speed in that range also.

   If you have a laptop record the sound while its stationary. and post it so we can listen.  Also try the old fashion way of locating the source.  1) With a screw driver press the handle to your ear and place the tip on different parts of the engine.  2) With a plastic tube, this will detect any escaping gas noises like leaking exhaust gaskets or inlet boots etc.    CP  Colin Prior  Cogmos Committee Chairman  Lake Forest Park WA  COG#7767

Ron, others have suggested the speedo as the culprit and that is where my noise came from. Mine was temp related as well. When the weather cooled it started in with a high pitched whine.  I lubed the speedo and it went away. I would try the easy stuff first. Good luck.  '02 Connie  COG # 6662  Dallas, Tx

My 98 also whines, at certain temps and always around the same RPM. Around 3000 RPM. I always thought it was gear related. It sounds like the whine from straight cut gears meshing. If I shift up or down, it goes away.    At 98K, I don't worry about it.  :)  Patrick    Ride safe.    1998 Kawasaki Concours Windsor Green    COG# 7292 CDA# 0135
