Electronic Ignition system

I have the Motorworks kit fitted to my 84 G/S, fitted very easily and quickly and uses the existing wiring loom no issues. You will of course need to strobe in the timing to get it bob on. Works well and runs extremely well.

The correct timing varies buy up to six degrees from bike to bike, so a strobe is not much use other than to get it running in safe mode.

The Boyer Microdigital system , or micropower if you need a coil, fits into all bean cans with a bit of trimming and cuts the cost by about half, which gives you a allowance for a bit dynotime/ whatever to get the timing optimized.

To set the timing just do what the guy on the dyno does, set it buy ear to best tickover, which is usually just below the fastest tickover, then do a couple of test runs , if possible up a decent sort of hill where it is pulling hard, or on a dyno if that is easier for you.

I read somewhere that the 32 degrees advance figure is a bit misleading , as it refers to having the z mark lining up 3200 revs. But most ignitions keep on advancing after 3200 revs, so the maximum advance is nether 32 degrees or at 3200 revs, on most bikes.
 
Setting the system up isn't the problem, I can do that, I've got two systems both set up fine but when the ignition control unit gets warm after five or six miles the revs will not drop to tick over properly, they hang at around 1800-2000 rpm, if I put the original ICU back on the revs drop to tick over but of course it won't rev properly having no advance.

I have swapped the ICU's from both systems but the problem persists I have also swapped the bean cans with out a cure (not that that should cure it)

Put the original system back on, back as it should be!

I'm suspecting a problem with this batch of ICU's. I'm using the single plug 26deg system.

Ocams Razor... are your throttle cables routed properly?

They are indeed, I always use a single cable to a splitter, I've had them all off and changed the end cables and the splitter, also rebuilt the carbs (just to check) but when put on the original ignition system , it's fine (even better than it was have refurbished the bean can).
 
Thank you all, the problem is now cured, I have the system running on two bikes fine but it won't run on the other, I have cured that one by other means.
 
Boyers can often vary a bit as what revs they reach full advance, usually around 4000 rpm, so the trick is to set the timing on the F/Z point when you see on the strobe that the unit has stopped advancing, ignore the Rev counter.

If you have a micro digital don't try and set timing on the S mark, because The Boyer micro uses ignition timing to catch any stalls, so the timing curve is V shaped below about 1000 rpm.

Go on, give us a clue !
Never used the Emerald Isle system myself, but have had a nightmare with the Boyer Bransden Micro Digital on my twin plugged 100GS PD. Even Rob Farmer gave up, and I ended up returning the whole shebang to Boyer, and got a full refund.
It would either run OK at low revs, and un-rideable at high revs, or vice versa. I also would get the whole ignition system cutting out once it got hot. Put the original beancan system back on, and all was fine again. And that's how I left it, with the original beancan:)
 
Revisiting an old thread, any developments lately on the electronic ignition front?

I'm running a twin-plugged '93 paralever with dyna coils and am thinking about going digital. Motorworks have a system that looks suitable, replaces the bean can and has a curve for the twin-spark. Then there are the Enduralast, SilentHektic and Sachse systems. Maybe others? The Boyer looks like if only works with the earlier bikes, is this true?

I'd be hoping to find easier starting, perhaps some small improvement in general running and also to eliminate the sticky bob-weight high tickover issue. A cost-effective upgrade would be good.

Thanks for any ideas or experiences

Looking to change mine too would be interested to hear what are the best options
 
Some folks have trouble with the Boyer, some folks dont.
All mine have performed perfectly out of the box and have been fit and forget, but I am led to believe it is possible to screw things up if you are ham fisted enough.
You dont say what sort of resistance the Dyna coils you have are and that will probably make a difference as the Boyer Microdigital is designed with a points system.
It is possible to get the Boyer working in a Hall sensor can, and the Micropower system includes excellent coils in a price that is probably less than others charge for their systems without coils.
The Boyer twin plug curve is excellent too, but cant comment on how it compares with the others.
 
Thanks for the info Beemerboff. Not sure what resistance the dyna coils are as sourced them many years ago. I'll whip the tank off and measure up. I'd quite like to try the boyer out but am reluctant to mess up my working hall-effect bean can. Maybe I'll see if I can get hold of a knackered one from Motorworks and have a play. Only problem I've had with boyer systems is they can be reluctant if the battery is low although I understand the newer versions are less sensitive. As you say, maybe a system with new coils could be the way to go anyway

Anyone have a knackered bean can to sell?
 
I have a points bean can which housed my Boyer electronic ignition bits, so you can have it for £20 posted?
The Boyer parts fitted in pretty easily. You need to use the old points bean can as it has the securing screws/bolts in correct place for the Boyer fitting.
 
As it turns out my brown dyna coils are 1.5 ohms each.

Boyer's website only lists the micro-power KIT00305 BOX00241 for twin-plugged 79-80 whose data sheet states it should be used with 2 "special digital" micropower coils. Price unknown at this time but presumably not far off the £225 being asked for similar micro-power setups.
Motobins website only lists the Boyer micro-digital for twin-plugged 79-80 for which they recommend some PVL coils whose resistance may or may not be less than 1 ohm. Price £244 including coils.
Motorworks list the Alpha system for twin-plugged 81 on which works with standard coils. Price £236.04

No cheap option yet that uses my own coils....
