#7777 Coolage (User) Fresh Boarder Posts: 44 Hi pitched noise 5 Years, 10 Months ago   I have a new 2006 Road Star that I now have 1500 miles on. Since the break in is over I have reved it up a little more. When I get to a higher RPM I hear a hi-pitched noise. I have no idea where it is coming from. Any ideas?

And I'm 99% sure it's from the motor. It gets a little lower pitched when I let off to shift and then goes right back up. I don't know if it's tied in to my changing my PMS setting but it seems to have started right after I turned my PMS in 1/4 turn. And I did it at right around the same miles you have. But I don't know if it's a bad thing. To me it sounds just like the whine you here when a V twin pulls up next to you. Harleys make that sound at all RPMs from what I've heard.   Logged       The administrator has disabled public write access. #7786 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 17615 Re:Hi pitched noise 5 Years, 10 Months ago   Does it sound like a sewing machine? If so then it's just the gears.

You know, that noise. I had a 64 El Camino that had a good tight 327 that made the same high pitched whine. What has me curious is why it didn't show up until I turned the PMS in. I don't see the connection.   Logged       The administrator has disabled public write access. #7798 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 17615 Re:Hi pitched noise 5 Years, 10 Months ago   Musky wrote: The noise on mine I would describe as the tight powerful motor noise.

I don't see the connection. Air movement through the intake? The air moving through my BAK makes different noises depending on the revs; it increases in pitch as I rev up. Would a PMS change result in a different noise. Hared to say. But I know even after all these years I still hear an occasional 'new' noise that usually turns out to be an 'old' noise that I've tuned out.

If I let off to 78 mph the noise stops. If I ride even harder that 80 it is still there. It sounds like it comes from under the gas tank or up front somewhere. Kind of an irritating noise like a high pitch of air whistling thru a small hole. I have Vance and Hines Power Shot exhaust with Dynojet needles and jets in the carb. It was all set up like that when I bought the bike new from the dealer. At first I was getting around 30 mpg. I called Dyno and they said to move the needle from the 4th groove from the top to the third groove from the top. It improved to 48 mpg last Sunday. Before it was so rich it would blow black smoke when starting it. It sounds better now. I wish I could get rid of the darn buzz.

Sometimes you can get a whistle coming in between the headlight and the headlight cut out in the windshield.   Logged       The administrator has disabled public write access. #7804 DocShadow (Admin) Hmmmm .... send beer Admin Posts: 17615 Re:Hi pitched noise 5 Years, 10 Months ago   Coolage, Don't hear much of it any more but it could be your headlight. When you hear the buzz place your hand on the top of the headlight. If it goes away we can provide a fix.

I have tried pulling and pushing different directions while driving to find the noise. No Luck. I will try the headlight thing.
