Cylinder identification sensor.

It's a sensor of some kind. Fooled me self by cleverly hiding the wiring to protect the sensor.

Thanks Ross!

Sucks to get old, Eh. memory retention diminishes.

My first guess was camshaft position - changed reply to cylinder identification after looking at FSM. Couldn't find it (named as such) in an on-line parts fiche

For tach maybe? IIRC the sensor sits directly over a cam lobe.

Don, once you are finished with this project, know what you are doing and it is still relatively fresh in your mind, you should come for a visit and go through my bike. Just remember, all three conditions must be met before you start work.

Yeah, I think it’s the speed sensor, item 24 on the Bike Bandit electrical #1 micro fiche diagram.

Fiche says speed sensor. FSM says cylinder identification sensor.

According to the '06 service manual, the Cylinder Identification Sensor is on top of the cylinder head. It has three loom wires coloured Blue, White/Black and Black/Blue. The wires to the sensor itself are White, Blue/Yellow and Black/Blue.

The only "Speed Sensor" in the '06 Service Manual is for the YCC-S variant, it is buried in the back of the crankcase.

My assumption is that the parts fiche is incorrect - I looked at fiche(s) from a number of suppliers (for non-AE model) and they all seem to identify the part as a speed sensor although the only speed sensor in the FSM is related to the YCCS. The Cylinder Identification Sensor is mentioned numerous times in the FSM.

Let's just call it a "sensor"!

I know, I'll unplug it and see what doesn't work

I do not recommend that technique. We tried it when ole Aunt Betsy was in the ICU.... did not turnout well.... for Aunt Betsy.

Well, then again, many a FjrForum peep has *SERIOUSLY* recommended I part this old gurl out.

But I can't!

My goal is 1,000,000 miles on bikes *currently* in my stable.

And KrZy8 is a major player!

To add to the confusion, the Haynes manual identifies it at a CMP or Cam position sensor, consistent with RossKean's first guess.
