Thanks Kawazoki...
I'm staying the night at Dimitrograd a few km from the Bulgarian border....
I guess I'll find out in the morning.....

Worst that can happen I buy another policy and learn a lesson.....

I made it into Bulgaria without an issue. I might have confused them with the whole Britsh passport/Australian vehicle papers.

"You British? Bike from Australia? Drive on. Next please....."

Note to self: Don't do that again.....
