Hi
As per the title. Looking for a new ignition system. I am still running Interspan.
(I have a few lol) all quite old.
Setting up the timing & how it's charged are important. But need to know what's out there in the near future.

For the last two seasons I have been using a crank triggered Boyer with the Twin coil ,not to expensive but you have to provide your own trigger. It works well ,not programmable ; the only problems i encountered were mis firing when the fairing rubbed on the pick up coil, and when the trigger I made fell apart, this caused a further problem at a later meeting when the pick up trigger coil bracket fractured . All in all pretty good , starts well and runs well its a total loss system but the current draw is pretty small so a well charged battery ( mines 4 years old ) lasts for at least 3 days without charge . Only downside is that its a bit vulnerable if crashed , so I try not to crash.
I have a Rex Caunt crank triggered battery less ignition on my race bike.
Fool proof and accurate
He makes components for BSA bikes, and a while back listed Commando ignition systems for sale, so not sure he makes them now.
Try RCR (Rex Caunt Racing)https://rexcauntracing.com
I would contact him by email to see if he still makes them as there is very little listed on his website.

Did you buy the Boyer box from Steve Maney, or is your advance curve the same as a cam driven curve?
I ran my Many Boyer box with a cam pick up for a while, and of course I had half the advance! Didn't seem too big an issue, but I think it would be worse the other way around?
...............i did want to make one like ralph's but with the thicker Maney cases and 40mm belt I couldnt make it work in the space available............!
And therein lies my concern, 40mm belt and Maney cases.....but I think that is what Ralph has?
As Steve says, I run an Ignitech ignition. It is programable and seems to work with just about any trigger, I have a small 5 AH LiPo battery and haven't run out of sparks yet.
Once you have it set how you like it, advance curve, rev limit, shift light etc, you can lock the program and then it is eligible.

€158 for the control unit.
€9 for the harness
€15 for the pickup
€25 postage.
Yes, but the previous owner had had the cases machined for a road chaincase. It has worked to my advantage because of the relative ease I managed to mount the pickup but I would rather have the extra strength in the cases.
I suppose it could have been easier to mount the pickup onto un-machined cases as there is plenty of meat to fasten an L shaped bracket directly to the cases. I see no reason why the pickup needs to see the outside edge perimeter of the rotor, it should work just as well facing the outside face of the rotor, ie facing into the engine.

How did you calculate where to place the rotor 'blade'?
If I remember right, the trailing edge of the rotor is at TDC when roughly at 3 o clock. The pickup was then mounted so I could get 26deg of advance. (920)
I don't mean flip the pickup. More fit it 90deg and face it to the outside face of the rotor, it would still see the end of the rotor lobe.
I am guessing you can do a two step installation, run it with a cam pick up before developing your crank pick up for example.
Really, they are great value. I spent more on two Pazon boxes!
