Confused by my indicators.

(1/4) > >>

DaveB:
I'm still finding out much about the CB750K6 I've purchased and I'm sure I will be for some time, but I am currently confused by the indicators and another anomaly.

The bike is I understand a K6 (manufactured in Dec 75) for the US market.

First the indicators. Having a good look around the forks and headlamp area I came across what I now understand is a warning buzzer for the indicators. However, I can find no way to make it sound. Assuming for now it's not faulty or there's a wiring problem, the user manual (downloaded PDF for a 76 CB750) makes reference to a range of movement beyond the normal switch position in which the buzzer will be activated.

However, the switch on my bike doesn't have this additional movement. It switches left right or middle with no other positions available.

I'm just curious if this could mean anything about the age of the bike or if it's had a new switch unit from the wrong year fitted?

Second point is the throttle switch unit which is fitted with a screw to tighten the throttle grip (it seems). Yet, I can't find mention of this in the user guide. Does this also point to replacement switches or something to do with years?

Sorry for the questions, I'd just like to understand my bike and all it's foibles.

Thanks,

I cant see how you will have a separate switch position for buzzer function.
buzzer should work from main indicator switch  to flasher relay..proabley more than likely etc..
good luck  :)

Trigger:
If you never ask a question, you will never find the answer.
The buzzer should work automatically when you operate the indicator switch but, many people find them a pain in the arse and disconnect them. Or it doesn't work anymore.
I have a UK, K6 in original condition and when I have time later will put some pictures of the switches on this page. 

Trigger:
These are UK, K6 switches but, a little different than the USA units.

DaveB:
Thanks guys. The left hand switch pod on mine looks identical to the UK one. The right is different in that I can't turn the headlight off. I can't see from from the photo if the there is a throttle tightening screw underneath?

Even the circuit diagram for the K6 (as well as K1 to K5) indicates (oops) there should be separate positions on the switch...

L1/R1 are without buzzer and L2/R2 are with.

It just seems very odd that the diagram and user guide would refer to this second position when it doesn't physically exist on the switch.
