I don't think your whistling is related to your chain adjustment. What else might be whistling ... helmet ... ???Did you change anything else? Was your chain loud before and possibly covered the noise you are now hearing?

Some times the toner has a clear plastic tape that is inside the toner, the tip is on the short side of the toner cartridge. if you do not remove that plastic then it would make that whistling nosies.

usually a whistling sound is from a vacuum leak

Sounds like a throwout bearing is dry.

If it is whistling while you rev your engine (while parked), then most likely there is a leak or hole in your air intake or vacuum hoses.

Facts:
1. Your car creates a vacuum to constantly receive air from the outside.

2. A whistling noise is created when air travels through a hole.

Check all air pressurized ducts for holes or leaks.
Check air intake system for holes or leaks.

a couple of things could make the tv chassis whistle
1 coud be dry solder joint probably on power capacitors
2 IF your tv has tube the board on the back could be making the noise its to do with the yoke on the way out!

you most likely have an aftermarket radio installed
the noise you hear is engine noise, if yo turn your radio off it will go away
this can be fixed by either getting better wiring for your aftermarket radio or by installing a noise filter, you can purchase that at most big electronic stores
