Thanks for the welcome Weldangrind, I don't know if anything from this motor could be swapped. Judging by the way it performs compared to my QingQi and Galaxy air cooled motors, I think you are wise to stay with the air cooled design...they seem to have more low-end grunt.
Oengus, the Chinese motorcycle industry is at least a decade away from the king of traceability and accountability you envision. I'm in these factories all the time, and very few follow ISO/TSA protocols...yet they all have the certificates hanging on the wall
Cheers!
