Excelsior 500 Works Racer - Magneto Advice

[Vincent Brake]

hello Gents, finally found it. 1939, GJD 500. one for my collection Cammy prewar UK bikes!! AND a riding one!!
Its even got a Dutch license plate, alltough ZZ (indicating only permitted on the road to go and ride on a rally)

its a TT magneto (maybe BTH), and here, being a mechanical kiddo, all my knowledge is failing, so i always ran a Mile when near a magneto.

It has been standing still with a dripping petroltap yust over it, so a long time soaked it it i guess, NO SPARK.

Where to trustworthy send it for repair? maybe PM me please?

Take the points assembly out and give the contacts a good clean, re fit and try again.........This works many times on bikes not used for some time.........simple enough and worth a try.......

Yes it is definitely BTH. It is stamped BTH on the housing. Hidden by your hold down strap. You can see the stamping in the photo.
