Well I passed this morning and it was still there, I thought I would leave it as I was coming back the same way and it was early when I was passing - bike still there so I took the reg and pulled in next to a local Police car to report / offer recovery to a safer place.
Police, did a PNC check and found the owner, I offered my number in case owner was struggling - all is OK and it should be being recovered as I type, it seems to have suffered a blowup of some variety.
Gorgeous example, nice open Termi's very clean, I guess it was just lucky that it survived the night without being lifted - hope after investigation there is a happy ending to the engine problems !
