Right had a look at everything I could think of today.

Other strange thing today was that it started ok (ish, still struggled a little) and would sit there and idle by itself. But still reliably idling high in gear. When you rev in neutral it returns to normal idle speed, when put in gear it stays at normal idle, once revved it doesn't return to normal idle until you knock it back into neutral.

Started by checking for faults in the dash, nothing recorded. Whilst in diagnostic mode check all other channels, Throttle angle, lean angle switch voltage, vehicle speed pulse etc. Also checked the sidestand & neutral switch were operating correctly through diag mode.

Also checked for clutch switch operation. It registered continuity part way through pulling then clutch and then died off when closer to the grip, don't know if this is normal.

Checked Crank position sensor. Range 192 - 288ohm. Read 280ohm.

Checked Ignition Coil.
Primary coil resistance range (@20c which it wasn't today!) is 3.4 - 4.6 ohms. Read 5.0ohm.
Secondary coil resistance range 10.4 - 15.6 kohm. Read 23.42 kohm
Pretty far out of range, anything to do with closer to freezing temps today??

Checked as much of the harness as I could for any frays/rubbing etc.

What do you reckon?
