Welcome to the forum.

What sort of configuration is the motor?

BSA manufactured the Lightning (2 carb) and Thunderbolt (single carb) 650cc, parallel twin motor. Late 1960's to early 1970’s.

I don't recall there being anything along the lines of "M lightning bolt P" stamped on them though.

Could you post a picture of it?
