Clutch lever switch (Breva 1100)
« on: September 29, 2015, 02:55:06 PM »
The guy doing the safety inspection on my Breva 110 pointed something out to me that I'd never noticed.

He showed me a switch underneath the clutch lever that would allow you to start the bike in gear by pulling in the clutch.  I had never noticed it or missed it, being content to fish for neutral on the rare occasions that I stalled.

The switch guts are in place and evidently work, but there is nothing attaching the clutch lever itself to the switch.  Should there be some sort of toggle or sub-lever beneath the clutch lever? Am I missing something?  Could it have gone missing?  Can I get one?  Were some bikes sold like this?

Looks like it's actuated by a "plunger" built into it:

Thanks Charlie - all that illustrated is present on my bike, but nothing to activate the switch.

There's sort of a flat "lever" that is attached to the pivot for the plunger which activates the clutch master on the bottom of the clutch lever.

I think for it not to be there that it would have needed to have broken off, but that seems unlikely.

I'm sure someone has a picture or a diagram to illustrate my poor description.

I suppose the stock lever was replaced once with non standard cheap replacement

On the cheap lever I bought, I had to reuse the original pivot and hence the original clutch switch activator. Maybe a better quality lever was purchased, but not good enough to get everything.

The switch is item (2) in the top LH corner.

Since it's an input to the ECU (very low current) you may be able to make something using a reed switch and a tiny magnet.
