Fit & forget the Boyer Bransden Electronic ignition. Easier starting better running its a no brainer!

Bri I can understand that if you have a BB unit fitted and not had any trouble then to you it is a "no brainer"

My personal experiance is different, I bought a Velocette Venom about 10 years ago with one fitted, if I ever found myself in heavy slow traffic or similar the bike would start spitting, farting and mifiring until it eventually stopped, restarting was impossible for about half an hour or so until everything cooled down I suspected the BB unit and sent it to BB for testing they said no fault found the fault continued until eventually I was brought home on a trailer the BB unit dead. I manageed to find the correct BTH mag for the bike rebuilt it and guess what? problem solved no more trouble in traffic.

I also marshal quite a bit for the VMCC and in the past two years have had two other people stuck at the roadside with dead BB units. No brainer?, possibly not.

Hi Bertie, I recently fitted an Indian made electronic ignition (available from our hosts).It costs far less than the Boyer unit and so far has made a big difference to starting and smooth running. My view is that the Boyer unit is probably a bit too sophisticated for the bullet. I'm no expert and no doubt others with more knowledge may disagree.

Hi All. Just to report that Connie's Pazon works perfectly, now I have the carb sorted. 1st or 2nd kick starter, and no stuttering, missing or stopping! Mind you I've nothing to compare as when I got the bike, the Mag was bug*ered! Good luck, Stephen

True points are easy to maintain and fault diagnose, with spares, cheap and easy to carry somewhere on the bike.

However despite this i may change to electronic one day as it becomes more of a faff trying to maintain a half useful advance curve with a fourteen year old wearing out mechanism..

New standard springs advance too early..

Uprated springs too much retard..

Now use one of each and is acceptable at present, unless i forget and give too much throttle whilst bimbling in high gear..

Just maybe the electronic would be kinder to piston and big end..

Have you looked at the production quality of a set of points recently, cheap though they are..

Some the faces don’t even meet flat together out of the box..

Pros and cons, Sit here on the fence until forced to do something i expect..

Hi Stephen, I fitted a Pazon on a Meteor and that thing starts if you just lean on the kicker, at least with my Inter, no chance of anybody getting on it and riding off, they would never get it started

I converted to electronic last year. Haven't had any problems with it. It just works....

I converted my 535 bullet to digital electronic after talking to our hosts. It cured a pinking problem as it has a better advance curve than either standard electronic or points. The 535 Is now a 612 using only a 3mm compression plate and still no pinking. It made no difference to the starting which has always been good and I'm not sure you would notice much change to a
standard bike other than it really is fit and forget.

Digressing slightly (apologies) but I am interested to know, Bobw, if your 612 has the Accralite piston? I ask this because I could only eliminate pinking on my 612 (using points ignition - with the stronger A/R springs, Accralite piston and either BP Ultimate or Shell V-Power petrol) with 5mm of compression plates. If you have indeed succeeded using just 3mm and the Accralite, then I would agree that the digital ignition made all the difference. Mine is running great on 5mm so I'm not going to change it, but it would be nice to know! Cheers!

HI Barry. Standard HItchcocks 612 kit, I don't thrash it and the piston and cylinder was run for around 300 miles as a 535.The engine was carefully built with no real problems and I do use a dash of valve master although I still don't get pinking on straight unleaded. The static timing is spot on both using a disc and a DTI and I've left the advance timing to the digital ignition the timing gears have very little backlash and the 'distributor' bearings are good. Mr H's advice has never failed me and I've spent £1000s with them. Brilliant bike now. Cheers.
