the best and most reliable results use a BT-H magneto for your ignition source.
Many thanks, received the
new mag and my 61 Bonneville is running better than ever.
I'm really preaching the BTH over here in Oz. I was
actually put on to you guys from a speedway friend of mine
that uses your mags in his supercharge Vincent speedway
bike. He has run them on all his bikes for years"

Hope you had a nice weekend. I finally got to ride my Gold
Star I put one of your Mag-Dyno's on last year and it ran
great!!! I've been trying to sort the ignition since about
2006 and finally threw up my hands and tossed the Alton
and Boyer and went with your Mag-Dyno. And that seems to
have sorted it! Many thanks!
I saw my friend Gus V this weekend and he is thrilled with
his BT-H on his Vincent and can't wait to get his BT-H
Mag-dyno mounted on his Gold Star. I'm telling everyone I
know about the simplicity of your BT-H magnetos and mag-dynos!
Keep up the great work!
I just wanted to drop you a line to let you know how
incredibly pleased I am with performance and looks of my K2F
style magneto. Not only was it a breeze to install and time,
I have to say the engine has never run so well AND has the
added bonus of fooling all my vintage bike loving buddies
into thinking it was a genuine Lucas mag! Many thanks for a
23rd July 2013
Just a quick note to say I have started and tested the bike
having fitted my new electromag!
It is a different bike now as it starts easily and pulls
progressively through the rev range!

I have just fitted a new BTH, FMR1 to a 1948 Mac Velocette
and I would agree with previous comments that it makes the
machine very reliable ( just as reliable as modern machines)
and easy to start. There are great advantages with the new
Magneto, no points, built in advance and very easy to
install and time. Congratulations on producing a high
quality product that will make older machines more useable.
