Hi, new member from South Devon. Got a Boatian 50 (2008) as a box of bits. Bit of a challenge to rebuild as I wasn't the one who smallerised it. Got the Haynes manual, I find that a bit generic, as there are so many similar models. So I could well post pictures of USOs for you guys identify, (I hope). Only ever owned one other scoot, 50+ years ago, restored scores of MCs though.
