My directional buzzer screaming like a siren
« on: March 10, 2006, 02:55:40 PM »
Today I went out for a ride. The first part of the ride I opened it up to about 75mph and everything was fine. I rode about another 12 miles and was on my last straight stretch opened it up to about 70 and what sounded like a high pitch siren came from my bike. It sounded just like my blinker buzzer except louder and constent. It stayed the same and didn't go away until I got down to about 15mph. Is there any other warning speakers on a 76' 550 that I don't know about? Has anyone ever had this sound that can tell me what it is? I felt like a cop flying down the road. I'm still laughing about it.

thanks

When the Speedometer internal bearings wear and get dried out, the shaft can walk around the perimeter of the bearing instead of simply turn inside it.  This is called "spooling", causes vibration, and makes a nasty racket that could be interpreted as a buzzer.

I had one that made noise in the morning when it was cold, but not on the way home when it was warmer.

I believe I finally lubed the cable and the cable socket in the instrument while it was upside down.  Just two or three drops of speedometer cable lube.  It hasn't done it again since.  But, I'm not sure the lube did it or if it just got tired of whining.

Did a cop follow you home?   Sounds like a cable/instrument prob.  Unless you found cat parts in the front wheel!!

Your wife hanging on for dear life and screaming like a schoolgirl? That's the first thing I'd check if it was me  ;D
