[QUOTE="Oldhaven, post: 110544, member: 2879"] Based on magneto problems with my newly rebuilt Rapide I started working with Power Arc three years ago to adapt their multi spark and programmable ignition to 50 degree Vincent twins and singles and to fit it in Bob Larmour's design for a magneto replacement housing. This is very similar to the Power Arc ignition that Old Britts sells for Nortons, less the housing. It has also been adapted to HDs, Hondas and even automobiles and tractors over the years. One of our great old time Vincent owners helped get this going financially by investing in the first ten units after my prototype was installed and worked well. Bob and I are both using the ignition successfully on our Rapides, one other is running on a Rapide on the West Coast, and two are currently being installed on a standard Comet and Rapide, and two more on big bore Shadows. I am just now packing up one without a housing that will be adapted to a Rita housing by a talented owner, and Cyborg did his own adaptation to a Norton points housing of one he got from Power Arc directly. That is documented here on the forum. Like the JE steering stem, we are not doing this to get rich, but because it seemed like a good system with its standard advance curves and unlike some options was programmable, which is useful for special needs like dual plugs and competition. The system with housing runs from around $600-$800 depending on coil choices. The optional programming unit adds to that if it is wanted, and if you have a housing you think will be useable and are as clever as Cyborg, that will take about $250 off the total. If interested please contact me by PM and I'll email you a user manual to peruse. I don't anticipate providing many more systems as that will mean investing in another lot of Bob's housings, and they may be more expensive than last time, so we will see. l have 6 housings left from the first lot.
