    I am having the same problem with my 1998 Heritage softail. It does it first thing when cold but is getting worse. It only does it when the bike is in motion & not when idling or reving up in neutral. This morning, I think I noticed that when I squeeze the clutch lever, it stops. I am going to double check this tonight on my way home. What does everyone think ? Any ideas ?

I had a similar situation with a Harley once that turned out to be a broken front motor mount.

I do not work on many Harleys, but I was told that it was a fairly common problem with that model.

Maybe that will help, maybe it wont.

Horrible noise started coming from gearbox and noise continues if i pull clutch in and kill motor and free wheel! is this likley to be main gear shaft bearings and if so can it cause more damage


Hi Daddydogg, if it is a high pitch squealing noise it may very well be a bearing failure the best thing to do is not to run it anymore and take it to your local dealer or reputable shop and let them have a listen. You can drain the primary and check the magnetic drain plug for metal ants. For more information about your issue, please visit the websites below, and for specific information or questions please feel free to contact me at xlch@mail.com. Good luck and have a nice day.

WHAT CAN MAKE A BRAKE TYPE HIGH PITCH SQUEAL WHEN LETTING OFF THROTTLE


locating a sound is hard especially because you're driving. Most likely a high pitch sound especially when you let off is a vacuum leak, or leak around your airbox. Off the throttle the engine is at maximum vacuum. Look at hoses cracked or not properly pushed in

Can sombody please help I have a strange sound in my 2007 r1 motor if bike is cold the sound is not there if you floored it the sound is gone but as soon you slacking down the sound is gone as long as


Describe the sound; a low clunk, higher pitched tap. Does it increase with engine rpm? Noise that is present on deceleration is often in your valve train, cam chains particularly. Noises that getter louder as the bike gets hotter can mean the type and viscosity of the oil is too "thin". Write back some more symptoms. Good luck, it's an awesome bike

Bike has annoying ticking noise from mostly rear cyl..bike is a 2000 shadow spirit, with 33000 miles, i was told valves needed adjustment at 30,000 miles , along with timing chain adj.. is this correct?


Without being able to stand next to the machine and listen it would be very hard to say what the noise is. Valves are generally easy to adjust and if loud have a high pitched tick sound. Cam chain adjusters generally self adjust and are reasonably quiet. If the automatic adjuster goes bad it will generally make a clatter sound or a loud clack. One thing you have not considered, if the the exhaust gaskets in the head go bad or leak air, they can also produce a loud ticking sound. You often hear this sound in older V8 engines. It sounds like a lifter is bouncing around inside the motor but the sound is caused by a blown gasket between the head and exhaust manifold. If you experience some popping/backfiring during deceleration try replacing your exhaust o-rings in the heads. This may solve both problems. If the problem is internal to the cylinder you may need to change a bad cam chain adjuster. As always start with the cheaper fixes and work your way up. Adjust valves and cam chain tensioner if not self adjusting, replace the exhaust gaskets next, and if that does not fix it, replace the cam chain tensioner. Hope this helps.

Clacking noise at different engine idles on my Yamaha V Star


Lots of bikes make a clacking in the transmission , especially when cold at idle. Basically the engine accelerates and decelerates between each piston firing, and you hear the backlash in the gears slapping back and forth. Without hearing it I can't say for sure, but find someone else with a similar bike and see if it sounds the same.

Squealing on acceleration


Very easily could be rust and /or corrosion on brakes that is slightly rubbing when no brake applied. Would stop when pressure is applied when brake engaged. Should wear off very quickly as the brakes heat upon engagement. May be I said.

2007 FLHTCU Transmission Noisy 5th gear


Wow, valves and other related engine noises don't care what gear you are in, they still make the noise. However your motor may be "lugging" in 5th gear which can cause a symptom of an engine related issue.
You may have an issue with the actual gearbox its self.
There is a primary drive chain that may be worn which will cause excessive noise in top gear because it is putting the greatest load on the engine. This is what connects the engine to the transmission. I think there is a tensioner for your model that will allow you to adjust the free play in the primary drive chain. If not I strongly recommend replacement because this will cause major damage if it breaks.
