I now own a 1983 Angle bp-48s moped that i purchased for $40. After doing days of research ive got a good grasp of what this bike will ever need. For anyone intrested to help or learn about these im thinking of making a section on this site or my website to explain and wrap up the confusion regarding these bikes. Also anyone whom may have the owners/service manual to these id really like to link up. underneath will be my findings so far.
