Hi guys, I bought a K100RS and drove it back from the dealer over 130miles and all was fine. The next day took it out didnt get more than 2 miles and it cut out. No chance of it starting. All lights worked, engine turned but would not even try to fire. Anyway left it over night is some nice old ladies garage, next day it started. But the promptly died. So I took out the plugs to check for a spark, all was good, but they were soaked in fuel. So it seems like the injection system is just chucking out fuel? Anyone has this issue before, is it a sensor or ecu issue? How can I check?
Try to fill 1/2L ethanol to full tank.
The ethanol will suck upp the water in line.
In winter I allways put in 1/4L ethanol when filling up.
Here in Ssweden I sometimes mix normal petrol with a few L
of E85 at gas station. It is a mix of 85% ethanol and 15% petrol.

Fried the battery this morning. For some reason the starter motor wouldnt turn, but it was clearly trying to. So I think I need to put hand in pocket and get a mechanic on the job. :(

This soundslike an injector is staying open all the time and not shutting,you need to take them out and clean them in some solvent,or fit a new set.you can get them from sherlocks or motor works or motorbins,these are all good bmw spares suppliers in the uk.its common for an injector to become clogged with emulisfied petrol when it has been stood for a while.

hmm ok I am indeed a numpty. you put injection system down and I put carbs down.. what i was meant to say is there water in the fuel system. It sits in system and then you have to strip it down to get rid of it

Possible water in the fuel. I would check this first. Strip your carbs down and try again. Check all jets are unblocked.
