Anyone have experience with Boyer Bransden ignitions?

I recently purchased a SF2 that has a Boyer Bransden MKIII ignition. I am wondering if there is a knowledge base on this.

I will be using this SF as a track day / club racer. My only other experience with laverda electronic  ignition is the DMC I bought from Wolfgang in BC.

Any thoughts?
 
Hello,
have run that on my 750 for some time.
Was oK, but only has one curve with the original 40? advance.
If you pm me your email-address, I'll send you some documents
I've collected about it. The people at Boyer & Bransden were
very helpful, too. phil37 used to sell them.

Regards, Ernesto
 
Hi - I've always (and still do) use the Boyer Bransden ignitions on my 750's - sold hundreds - I run much less advance - usually nearer the 35? mark - depending on CR etc. - Regards - Phil
 
Clay talk to Motorworks..UK  , Cris is Laverda man so may know the nitty gritty on this . They retail Boyer Bransden Ignitions.

I have used Boyer Bransden on my airhead beemers and it is flawless.

Looks like an interesting option. Keen prices. I need to replace the ancient points on my blue SF1 at some point.

Noticed Laverdas aren't listed on the BB website, so which kit is the best to adapt? Anyone know?

Motorworks aren't a million miles from me BTW [1], if anyone needs boots on the ground to work out a feasible option (though I suspect Phil already knows chapter and verse).

[1] and here to there has got to be one of the world's best motorbike rides :-D

Good reliable ignition but a bit short on advance range for a Laverda.

Well I'm at the point to start getting the engine parts sorted for the caf? I'm building for the track, and to hopefully make it "just "legal enough for the road. Reading through the comments once again it's a bit challenging to get the feel for what I need.

Phil, help  :-\
 
Hi
I have a very unused SF1 (re dvla poor service) that has a Pazon Surefire fitted, this was adapted by my pal of 40+ years an engineer and all I can say is it started first time after a full rebuild. The bike is still very new but it starts first go and runs clean through the revs up to 4+k still running in.
Paul my Pal has fitted many types of ignition systems and likes Pazon having it on his Combat Commando that gets treated like he stole it daily, he thinks its a simple job to fit to SF engines paying attention to the rotor mounting and using their own coil pack.
When on the road finally will give a 1000k review.
Cheers Coventrykid 
 
I've got some of the adaptor plates that take the BB stator plate (68mm ish) and also some of the magnet holders to fit on the A/R unit. I only have the magnet holders in aluminium - Ernie Bransden was surprised they worked as they were non - magnetic and I took his advice and had them made in steel. I did thin some down and mount the BB magnet plate on them. If anyone wants them - PM me. I don't want to get into selling ignition kits again as  I then end up with all the problems of anything else that is wrong with the bike and, in many cases, owners lack of skill & knowledge. The BB kits for the Jap fours have a box with a longer advance range - never needed it myself - but may be useful for others. - regards - Phil

Hi
Just got the reg number so SF1 on the road, been out this afternoon for about 60k ran really clean from low revs and pulls great through to 4k+.
Pazon seems to work very well first time starter as well.
Good luck Coventrykid
