Just finished my first build about 2 months ago. This forum is a great help with trouble shooting, installation tips and info. I bought the bike before ever thinking about a MB build, it was a challenge but well worth it. GT Falcon, 66CC, MM adapter with 40T sprocket from Pirate cycle. I just recently purchased the HD-12 Ga front wheel with the Sturmey Archer drum hub from pirate as well. On my second gallon of gas so about the third tank. and everything is so far so good. Just wanted to say thank you for all the helpful info. P.S. Any others close to my neck of the woods??
