GL1100 steering head mystery sensor?

Post by Sig45227 »



Anybody have any idea what this is? I pulled off the cover underneath steering stem hole between the Fairing and the fender so I could lift the bike and take the front wheel off.

Inside of the steering stem hole is this small cylinder with a couple wires on it.

Is this some kind of a sensor?

What the heck does this thing do?

More importantly how do I disconnect it, where is the source?

I believe you are talking about the turn signal cancel unit.

Such a weird place to put this! Not sure how to detach it so I can use my front end stand to push the bike off the ground through the bottom of the steering stem.

It needs to detect the steering position, so that is an ideal place for it. If you unplug it, you will have to jump some wires to keep your turn signals working. If you search here, I'm sure I read something about that if it fails, as it's no longer available, and how to get the turn signals working again. Do you just need to remove it while you are working on it, then put it back when you are finished? Or do you want to remove it permanently and lose the self cancelling turn signals? I seem to recall there are issues with doing that on some versions as you also lose the push to cancel function. Maybe someone with more four cyl. knowledge can elaborate.

I really just want to remove it so I can service the bike. When I'm done it's staying on the bike.
The self-cancelling signals on my machine work okay. Yes they are not perfect and they shut off probably when they shouldn't but it's a minor annoyance. I don't drive this thing in traffic.
I did do some searches and saw a couple people talking about the issues they have with the self-cancelling function. Makes sense where it needs to be. Obviously it's working off of speed, distance, and motion.

The front end lift that I have uses a peg that goes up through the steering stem, so the sensor and it's wiring need to be out of there or they will be damaged. Or shoved up so far that you can't even get to them anymore.
That would create a hell of a lot of work to get them out.
Thanks for the help!

You remove the two bolts, that's what holds it in on the bottom, along with the bolt holding the fixed wiper to the frame. You need to disconnect the connector on the wire on the top that feeds down the steering stem, then push that wire down into the stem, which will give you enough slack to access the bullet connectors from the bottom, which you can then disconnect, so you can remove the cancel unit.
