BTH Components Ltd.
A traditional Mag-Dyno for people who want to retain their original appearance and combined dynamo and don't want to rely on a battery charging system.
The Mag-Dyno was fitted on thousands of bikes ranging from the everyday work horse to the sporting BSA Gold Star's.
This is a replacement for the "tired" mag-dyno's that were fitted to hundreds of thousands of British bikes. The BT-H, MD1R mag-dyno is for people who want to enjoy the benefits of modern ignition technology and be able to refit an original dynamo without having to upgrade their machines charging system. This is an all new manufacture NOT a conversion to battery or renovation with a rewind.
This gives you all the usual benefits of a
new BT-H magneto. You get a new mag-dyno with electronic
advance/retard, proper journal bearings mounted in sturdy steel housings and no
contact points requiring adjustment or replacement. It is supremely
easy to time and because it is a magneto you won't be stranded if your battery
or charging system fails. A very small, external, high tension coil is
supplied with this instrument. This can easily be fitted in any suitable
out of the way place on the bike.
Email, write or telephone to order.

Harris' 350cc Ariel / Norton special.
Below is an email testimonial from Ray Pobjoy who has one of our mag-dynos on his Goldie.

I thought I would drop you a line to say that I received the Mag and have fitted it. I took my time so I could go about it in the best way to suit me, hence the delay. I set the timing to specs I could glean from other GS owners and from original tech info, then followed your instructions. I can't tell you how happy I am with the result. I am no longer terrified of starting the beast. No more savage kick backs, worries about getting advance and retart just right. No more worries about not being able to start it. Six kicks and you start to lose it, frustration, embarrassment and all your mates waiting around. It would put me off riding it a little I think, wondering how many times on a ride I would have to stop. From the first moment it started first kick. It is like a pussy cat to start now, but still has the cracking pace and sound. It looks original and all round it is an excellent result, so thank you very much for a brilliant unit. Thank you for the prompt back up support as well. I thought my experience and how I went about the process would make an interesting story for the GSOC magazine. Any thoughts on this?
Regards Raymond Pobjoy.
