#394738 brotherkram (User) Fresh Boarder Posts: 61 whistle noise with rpm change in neutral 6 Years, 8 Months ago   Hello, I have been putting up with this noise since I bought my ride last October. It just drives me nuts....The bike has to warm up first...then it starts... As you increase rpms it gets higher pitched. You can hear the noise with the bike in neutral as you increase the throttle. (clutch pulled in). I have checked for air intake leakes and put new gaskets in the exhaust manifold......and still the noise survives. 2001 roadstar ais removed 3 inch hk pipes. Any ideas?   Logged     The administrator has disabled public write access. #394755 Greysnake (User) I'm so far behind I think I'm first.

The only other thing I can think of would be that a vac line for the AIS was not plugged, and make sure the vent hose on the gas tank is still there. You have to remove the speedometer housing to check.   Logged     06 Midnight Silverado *nothing shines like a star*   The administrator has disabled public write access. #394794 Curt (Moderator) Never to old to ride!

That or you may have a crack in your pipes some where.   Logged       The administrator has disabled public write access. #394799 brotherkram (User) Fresh Boarder Posts: 61 Re:whistle noise with rpm change in neutral 6 Years, 8 Months ago   Air cleaner is tight.It is not an air cleaner leak. Gas tank breather is fine. Intake manifold has t golf tee put in the line. not leaking....The noise is coming from the front jug. It seems like it is coming from the front of the bike. Is it possible to get a leak on the valve cover? I did adjust the valves last year.... I will check the ais plugs .....Maybe that is it....   Logged     Last Edit: 2011/07/01 14:30 By brotherkram.   The administrator has disabled public write access. #394909 greenpus (User) Platinum Boarder Posts: 3215 Re:whistle noise with rpm change in neutral 6 Years, 8 Months ago   Some of these bikes have turbos on them   Logged     The administrator has disabled public write access. #394929 brotherkram (User) Fresh Boarder Posts: 61 Re:whistle noise with rpm change in neutral 6 Years, 8 Months ago   It is not the ais plugs. Sounds like it is low and up front where the ais used to be. I will probably have to get louder exhaust..   Logged     The administrator has disabled public write access. #394952 Greysnake (User) I'm so far behind I think I'm first. Platinum Boarder Posts: 15025 Re:whistle noise with rpm change in neutral 6 Years, 8 Months ago   you might take a look at the front fender tip to see if may-be there might be an air gap somewhere between it and the fender. Just a thought And I noticed you don't have the pie pans over the front rotors with all of those round holes in the rotors. OOPs you said it does it sitting still   Logged     Last Edit: 2011/07/01 21:44 By Greysnake.   06 Midnight Silverado *nothing shines like a star*   The administrator has disabled public write access. #395204 brotherkram (User) Fresh Boarder Posts: 61 Re:whistle noise with rpm change in neutral 6 Years, 8 Months ago   Stopped by the yamaha dealer in Rice Lake and they took a listen for the whistle....He thought it was gear whining. He said nothing to worry about ...very common noise.... So I guess the louder exhaust or just ignore..... I am happy again...
