Where can I find a motorcycle magneto repair specialist?


Motor bike | Vintage | Veteran | Classic | Dynamos | Starter motors  | Workshop service



Magneto repair work is specialised. For years we at Sump have been mucking around with classic bikes and motorcycle electrics, and would never consider breaking open a motorcycle magneto; mostly because we're lazy (and pretty stupid at times). But fortunately, there are still a few experts around who do excellent magneto servicing work at reasonable prices—and that leaves us free to work on Sump Magazine.


So if you need a repair to a magneto, dynamo, dynastart or regulator, try these guys. They're not listed in any particular order, and we've no personal or commercial connection with them. But we wouldn't list them here if we had any negative information about them. Any fair and balanced feedback regarding these specialists that's offered in good faith is welcomed.






Dave Lindsley

Vintage magneto, dynamo and starter repairs

Unit 22, Evans Business Centre (now FLEXSPACE), Enterprise Park, Brunel Road, Leominster, Herefordshire, UK, HR6 OLX

Telephone: 01568 617750 (from the UK)
0044 1568 617750 (from overseas)


Magneto timing detector


Dave has been around for a long time and has built a good reputation on the classic motorcycle scene. He services and repairs magnetos, regulators, dynamos, and starter motors. Ask him about his interesting magneto timing detector device (image immediately above). This box of tricks takes the guesswork out of setting accurate ignition timing. Beyond that, we'd be happy to trust our own magnetos to Dave. But see who else is on this page before deciding.








Armoto Ltd
Unit 26, M1 Commerce Park, Markham Lane,

Duckmanton, Chesterfield S44 5HS

Telephone: 01246 826667


These guys offer a one year guarantee on repairs, and a three year guarantee on reconditioned items. Maybe all magneto service and repair shops offer this. We haven't checked. In any case, you should always ask about warranties/guarantees.


But right now we're talking about Armoto which is standing four square beside its reputation and is evidently confident about the firm's work. It's a good start. This company offers repairs for alternators, dynamos, dynastarts, magnetos, armatures, field coils, rotors and stators. "From Faraday to Modern Day" goes the firm's strapline. Nice.








Brightspark Magnetos

No address listed: by appointment only

No phone number listed either



We know very little about these guys, but you needn't read much into that. There's a lot in this world that we don't know about, but (like yourself no doubt) we do what we can to address any significant intellectual deficits. What we do know is that Bright Spark Magnetos sells lots of parts aimed at the braver/better skilled classic biker who wants to tackle his own electrical woes and gremlins. At the time of writing, this firm does handle magneto repairs and servicing. And they've got a lot of helpful information on their website. If you're confident you've got the skills, time, tools and patience, this company might be worth checking out.







TJ Magnetos

29 Longbank, Birtley
Chester-Le-Street, Co Durham DH31PX

Telephone: 07917 274099


Lucas Competition magneto


This firm is run by hobbyists, but with a "professional" attitude. That's their basic stance. And that's fair enough. Most of the businesses in the classic bike scene are also hobbyists and are driven by a passion for bikes whilst hoping to earn an honest couple of quid. Magnetos and dynamos repairs (and the sale of parts) is what's on offer here. That's a Lucas Competition mag immediately above in case anyone put there was wondering.









Ribblesdale Auto Electrics Units Ltd

Deepdale Mill Street
Preston, Lancashire PR1 5BY

Telephone: 01772 796047

Bosch DU1 magneto

We don't know this firm, but we know a little about them. They've been around since the late 1960s, and they handle all kinds of electrical work for the automotive, marine and agricultural community.


Consequently, veteran, vintage and classic bikes represent only a small part of their business. The company generally offers a very fast turnaround of just a few days, but that will take longer if and when a magneto needs rewinding. However, we've put these guys on the list to increase your choice. A little open competition helps keep suppliers of services competitive. Are we right?
