Squeeking noise
09/11/08 at 14:18:07

Hello, I've got a bit of a problem. I've got a squeeking noise that is present whenever the engine is running. It almost sounds like change jingling in your pocket really fast. Opening the throttle increases the volume of the noise. I checked my valves and they're running to spec, and i've only got 400 miles on the oil. It sounds like it's coming from the muffler, but I don't believe that's where it is coming from. I know this is quite vague, but if any of you have any input that would be great.

It showed up after I had let it sit in my garage for a month while I was at Ft. Lewis Edit: The sound wasn't innate to the bike. The first 1000 miles were whistle free

Does it make the noise while standing still, or only when moving? From your description, it sounds like when standing still, so can't be belt squeak. How may miles on the bike?

Maybe a mouse crawled up into the muffler Cheesy

I would go over the bike carefully with the engine off and look for loose hardware, especially around where you think the sound is coming from.
Have the head bolts been torqued lately? This needs to be done after the first 600 miles, then less frequently.

The fact that the noise started after sitting for a month is probably a clue, but short of something crawling into the exhaust or intake, I can't think what it might be.

The noise is only present when the engine is on- i.e. idling, revving-, tried the palm pressure on the speedo, but it is definetely either coming from or travelling down the muffler. I checked the oil and it seems clear of debris.

If its not the speedo, maybe something literally crawled in it. Have you had it up to full speed? Is it lower than before you parked it? Any discernable differance in performance? Have you checked the muffler connections for leaks? If you smoke, smoke blown gently around the muffler/header connection might show something. Maybe theres a dirtdobber nest in the exhaust? I bet whatever it is will clear up if you'll run it up to 125 or 130 MPH!!! Grin

Aaaaaaaaa the famous VW whistle....... remember the old VW Beetles' from the 60's & 70's. They had that whislte too.

That has to do with the muffler internals , any type of soot build up or material breakdown for the heat changes the muffler from the Brand new tone.

The whistle happens at just over idle. Most noticeable when riding close to a solid object like a wall, a tall curb, a highway divider, etc etc.

My way of solving it.
see thread : Ain't whistling dixie no more..
