Description
Forsale is a magdyno unit which was fitted to a 1954 bsa b31, it had been stored for many years, ive completely stripped both mag and dynamo down, fitted new bearings and checked the operation of both, the mag produces the biggest spark ive ever seen from a mag, a good 1/ 2"long and the dynamo motors up once powered by a battery, both ive had running for 20 mins and they both continued to work well. Comes with drive gear and is the more desirable slack advance mag as fitted to the goldstar model. please ring mike for any questions on the details below
