Still havn't heard from the Police, other than the crime No, which is probably pretty par for the course.

I just had the steering lock on, but the fairly new VFR next to me had a chain around the rear wheel.

The chain had already been broken & was probably the next bike to be taken, when the scum was disturbed.

Other bikes had disc locks which I had always thought to be fairly easy to break, but may have been more of a deterrent than I thought.

Regarding the value of the bike, MCE make it clear in their policy document that they give you market value from something like Glasses Guide.

We parked the bikes towards the rear of the Hotel car park where they were shielded from view by other cars.
There was a 4' wall topped with 4' railings surrounding the Hotel, but of course an open entrance. 
We also think hotel staff may well have been in on it & tipped off the thieves that there was a valuable haul to be had. ( Only because there was a number of young workers there probably on below minimum wages )

The bikes were taken out via a delivery entrance 8' metal gate at the rear that was supposed to have been locked, but no sign of any broken lock laying nearby.

MCE insurance have been asking loads of the same questions in different ways like " is it used for work ", " is it used for deliveries ", " do I deliver Pizzas " etc, when I insured it SDP. They even asked for a picture of where it is normally parked at home in the garage WTF.
MCE have even scheduled a 30 minute telephone conversation with one of their claim staff for 2 weeks time to discuss the claim.
I expect they are hoping I will have forgotten some of the lies they think I've told them by then, but as it's all the truth i've nothing to worry about.

I'll update further as things progress.

" Meanwhile, will the throttle cables need changing? I think it's a bit of a job? "

I have the K1300R yoke ( you will also need K1300R bars ), I much prefer the more upright riding position.

I didn't need to change either clutch/ brake lines or the throttle cable.

I sourced from ebay.de for around £130 ( used but unmarked ).

Forget the above.

I've just checked the Reprom ( which I should have done first ) & although the above system is used in most car injection systems, BMW havn't used it on the K engines. There doesn't seem to be a fuel return line.

On the K they monitor the fuel rail pressure with an electronic pressure sensor & use this data to control the fuel pump pressure.

You could try some "easy start", brake cleaner, or carb cleaner into the air inlet.

If it doesn't fire then, you will know it isn't a fuel problem.

Have now got a pass for next week  , so booked into the Neuadd Arms Hotel.

Looking forward to seeing everyone next Monday.

Also check the dog-bone bearings, they have been known to seize.

Worth taking apart, clean & grease the needle rollers.

There was a set of wiring diagrams here https://eurokclub.bike/index.php?topic=83.0
The ones posted by Andym535, but I can't seem to access them now.

I did copy them to my desktop when they were accessible, so can give you that info if it helps.

There are 2 wires directly from the ZFE chassis controller located by the top left of the radiator Plug A21 & A37, to the fuel sensor connection on the fuel tank pump flange.

The fuel sensor shows as being a variable resistor.
It's the Gr-Ye wire at the sensor plug Pin2 & Ye-Bl wire on Pin3.
If you disconnect that plug & connect an ohm meter to the tank side of the connection you should read an ohms value that changes depending on the amount of fuel in the tank.

If you change your meter leads & look at the wires going away to the ZFE with your meter on Volts, you should see anything up to 12v with the ignition on.

Hope that helps.
