Thanks for all replies!

Not checked for error codes.. actually don't know how to check it... It's not in the service manual, is it described in the electrical manual? Is there a scanner you can buy for some modest sum?

The battery is new so it's clean so to say. Crank sensor makes sense, if it's not expensive I can just change it for the heck of it.. Will check the price today..

I might add that it doesn't happen 100% of the time, it comes and goes. However the warmer the bike get the more frequent it gets too..

Cheers Dyna

PS: Don't hear any leaks, but then that is pretty hard to hear. Guess I need to spray with some gas or similar to detect it..
