I have been experiencing a "Keys jingling" sound while driving at higher speeds coming from what I believe is the clutch. When I squeeze the clutch lever in slightly, the sound seems to lessen or goes away. Could the clutch cable need adjustment? Replacement of Clutch?
Ok the type of noise you're describing could be...
* cam chain
* piston wrist pin
* something dangling from the bike
* bad wheel bearing or final drive bearing
* loose exhaust heat shield
* keys rattling on the engine side case (never overlook the obvious)
* something broken or amiss in one of the fork tubes or shocks
* swing arm bearings
* ...
...
...
Next time out find a good size hill. While going down the hill pull your clutch and hit your kill switch. The only parts moving will be the drive train and the wheels. Jingling goes away then it must be from the engine or the exhaust. Good luck.
Hahahaha, I was thinking the same thing. That happened to me when I first bought the ACE a few years ago. I was like, "What the hell is that jingling sound?" ... When I put her in the air on the jack, that's when I noticed the stupid little bell. Funny, but true. :surprise:
Try to duplicate it while sitting still, then you can pinpoint it. If it happens at a certain RPM it may duplicate just gently revving in the driveway.
If it sounds like from an exhaust vibration, tap around the pipes with a rubber mallet. I used that many times on cars because it causes a low resonance vibration similar to road speed vibrations. You can do the same on the frame also. Maybe an engine mount bolt loosened. Even the engine side case may produce some sounds when tapping with a soft mallet.
On my 2001 1100 I had 2 rattles. One was a bolt that held the exhaust baffle. The other was a broken headlight diffuser. Once I fixed those the rattles were gone.
I was test riding a friend's bike this weekend after doing some work on it. Every time I throttled up hard it sounded like a broken valve or rocker, etc. At idle in neutral all I did was keep revving it and listening while placing my hand on every little item bolted to the bike. It ended up being the headlight trim piece ... it was missing a screw. Solved. :grin2:
I'm sorry, new to riding this year and I have no tach so I'm guessing the RPM. Let's say that it is above the cruising shift range, as if I was accelerating to enter a highway.
Check your exhaust heat shield brackets. Might be a loose one or a broken one. I had a broken one but more to the rear and buzzed at certain rpm's. Located it by slowly increasing the rpm's while sitting in the driveway.
I have a 94 Spirit 1100 and mine does the exact same thing since I got it 7 months ago, like a little bell ringing coming from the left front of the bike.
It's hard to explain which is why I never brought it up before. The bike runs perfectly fine and everything is tightened up as it should. It's not annoying, just curious what it could be myself. It sounds like one of those bike bells on an old bicycle.
I did a lot of diagnostics on cars for years, squeak, rattle, vibration and other noises. So you have to find a way to duplicate it easily every time then you know when you have it fixed.
Sometimes envision what is happening when you hear it. On acceleration the engine torque is forward and on decel it reverses so the drive train will be twisting the other way. With a chain think of the looseness on the bottom on accel and on the top on decel. Exhaust the same way = different forces when accelerating, or cruising or decelerating. Especially try to make it happen sitting still because that is the easiest to pinpoint. Or have someone ride next to you at the speed it happens and they may hear where it is from.
Ok guys after checking it over the weekend, I discovered the following. The bike makes the "jingling/Tinny" sound when the bike is at higher revs both when I'm riding or when I simply rev the engine in the garage. It is clear enough sound for another rider to hear when I rev it in the garage.
I stay on this subject, because I'm concerned that if it's an internal engine issue, that I'm doing further damage by trying to diagnose it. The bike starts right up, runs fine and power loss I can feel on the highway. Should I just succumb to the fact it must go to the dealer?
I have an old stethoscope with a piece of 3/4 inch heater hose a foot long that really helps pinpoint a noisey area. You can do the same with a piece of heater or garden hose a couple of feet long. Hold it up to your ear and move it around when you get the sound happening. You will need a helper to rev the engine as you concentrate on the noise. It will ease you mind if you find it is not in the engine.
Ok Forum, thank you for all the help and after doing the search you all suggested, I found the problem much to my relief. One of the bolts on the heat fins on the left side of the engine broke off. The heat fin was vibrating at higher rpm's. Now for the next task...removing the broken bolt. I am looking for suggestions on the correct way to remove this...
Thread a nut on as far as you can. Thread on another nut until it is flush with the outermost thread. "Loosen" the first nut against the second until it is pressing hard & won't turn anymore. Now you can loosen the "stud" by wrenching on the first/inner nut. Maybe. If the "stud" doesn't break. (Exhaust bolts are notorious for being hard to remove.) Then it's drill & tap time.
The double nut trick may work if there enough threads. It looks like it broke from vibration fatigue so it may not be too hard to remove. If you get a pair of vise grips down the stud as far as you can and clamp it very tight it may loosen and come out. Some times on a broken piece like that I would hammer on the end pretty hard to shake it in it's threads and that can help also.
Thanks for all the advice, the members of this forum were very helpful and I appreciate the feedback...the bike is up and running fine and no more foolish jingling sound.
P.S. I purchased some blue removable locktite so I don't do this to myself agai[/B]n
