OK, as the title says we have a 54 BSA A7 star twin 650. Now we have that motor and its sitting in a vintage chopper frame. We know it was a build from the mid 60's and has been sitting since the early 80's. I was wondering if anyone here know their way around this motor and could help with tune-up tips and what oils it should be running? Also some help with the basic wiring of this motor.
 Thank you for your time.
