Title: Under tank buzzer question
Post by: dpmacv on October 27, 2009, 12:48:58 PM
I  purchased a 1979 R65 back in June and have been having the time of my life riding again after a years long hiatus.  I love this bike and have enjoyed learning the ins and outs of these Airheads.  This past weekend, I had the tank off again to change the air filter.  I noticed what appeared to be a small buzzer located on the left side of the frame.  Curious, I looked at the wiring diagram (not my forte) and as far as I can tell,  this is supposed to buzz when the turn signals are operating.  Would I be correct in assuming this?

Thanks in advance.

Dave

It does indeed beep when the indicators are operated and quite loudly too.  The beeping stops when you pull in the clutch.

I had to quieten mine down with a bit of gaffer tape. It's still loud enough  to frighten predestrians into not walking out in front of me.

That's correct, from what owners of bikes that have it installed, they usually disconnect it, as it's quite annoying after a while .

Quite annoying is right - far too loud and high pitched. I disconnected mine and then had a near miss after leaving the indicators on. So  I decided the the beeper was not a bad idea after all an recconnected it with a bit of tape over the diaphragm.  It's now just about tolerable.

I've noticed there is a small adjusting screw and next time I have the tank off I might try adjusting it to see if it changes the tone to make it less annoying.

Yes it's very irritating...if you don't like it just pull out the twin connector under the tank nose, on the right side. You'll probably have to remove the tank. It's next to another twin connector which if you unplug it isolates the clutch switch, meaning that your neutral light will come on only in neutral, not also when you only withdraw the clutch.
I seem to recall that the buzzer is technically illegal in UK as it resembles the buzzers used on some pedestrian crossings to tell blind people it's ok to cross. If so nobody enforces it. But maybe be careful if you see a white stick.

...mm  I've had a search and can't find anything on them being illegal.

They were a late 70's thing I had a 76 Jap bike that had one (and that was too loud) then an 82 that didn't. Maybe they were a legal requirement only for a few years.

I still like to frighten predestrians but I do promise to be nice to pedestrians with a white stick. [smiley=smiley.gif]

Thanks for all your help.  Mine is already disconnected, so I think I will leave it that way.  Next time I have the tank off, I'll hook it back up temporarily, just to see how irritating it really is.

Thanks again for all your replies.

Interesting....I cant locate the buzzer may be the PO took it out.  Now i know what that switch in the clutch lever is for.....there is always something new to learn about these interesting machines.

I believe the buzzers were only installed on the '79-80 model year bikes for North America .

I used to unplug mine until I caught myself leaving a signal on.  Then I would plug it back in for a few weeks to teach myself a lesson.

The plugs can easily be accessed without removing the tank, if they haven't been tucked up out of the way.
Look under the tank at the front left side.

I think it is a good idea to have the buzzer.  I forget to turn mine off one out of 10 times.  Actually I was hoping to add a buzzer that i took out of a old computer (12v) and should not be too annoying.  Nice to know that it is already wired for one.  I hope i find the wires and they are not already chopped off.  So the switch in the clutch lever is to cancel the signals?

There are no wires installed in the wiring harness for the buzzer, after the 1980 model year bikes, for the US market at least .

No buzzer on my 1984 North American model. I have often thought of adding one though. However the clutch switch does allow me to start when not in neutral if the clutch is pulled in.

The electrical switch that's activated by the clutch lever, allows you to operate the starter when the transmission is in gear .

Not to cancel the turn directionals .

Correct. The neutral light means "neutral" if you disconnect the clutch switch. If you leave it connected the light means "ok to use the starter". Nothing more.

But it also silences the buzzer if you are sitting at a light in gear, with a turn signal on, and the clutch pulled in.
Let out the clutch, and the buzzer starts in again, until you cancel the TS (or pull in the clutch...).
