Question Boyer Ignition?

Dera All,

I have a Triumph T100SS from 1967 in good condition. It however seems to be lacking power and some un-even running of thje engine. I have read through a number of threads in regards to changing the ignition to a Boyer instead of the original. However I have not been able to find out the weight of the pros/cons...

In short. I am not a purist. I wanna ride the bike as easily as possible, I wanna ride it with light and for longer runs - Should I install a Boyer ignition? and if so - which of the models?

Thank you for you help!

Best

Tom

I installed a Pazon unit after messing with points on my bike for far to long and couldn't be happier with it. In saying that nothing wrong with a well set up and maintained points system, at least if the points stop working you have half a chance getting home, with EI its call a mate with a trailer time.

From what i have researched Boyer units are ok but there are superior units on the market now i would do some reading before laying out any cash.

Regards Ruger001.

Thank you! I have understood that it is quite a stabile solution, so thge "trailer-call" would be rare? I know that Panzon also are rated highly - what other solutions/systems are rated highly? Sorry for alle the (studid) questions but I am new to Triumph veteran-biking..

Any other comments or solutions I should be aware of?

Thank you again

Tom

Tom,
There are many different manufacturers of EI`s.
Pro`s: easy set-up and timing, no mechanical bits to wear out.
Once set shouldn`t need any further adjustments.

Con`s: Needs a good battery voltage compared to points.

You need to select one for your engine.
Boyer seem to have a bewildering range.
Personally, I use a Sparx EI and Rectifier/regulator.

I have a Sparx EI as a back up it works fine and i would have been happy to use it, i thought it had an issue but turned out to be a carb issue hence the reason i know have a Pazon and the Sparx is a back up. The Sparx was a great price and not bad kit for the money but is not the same build quality as the Pazon unit, the kit that comes with the Pazon was awesome and excellent install instructions, it even has a self diagnostic feature, battery can run down to 8 volt and they dont go full advance with low battery voltage, also 7 year warranty can't beat that for the money. It makes for a very tidy install under the seat.

I have also heard great reviews on a system called Tri-Spark apparently the entire unit fits in the points housing and those who have it installed love them but they are pricey, i am also a little concerned about the heat generated in the points cover, in my mind heat and circuit boards don't mix. But i dont own one so they may just be the bees knees, also they are made in Australia - they gotta be good!/

Having to get a trailer for bike with a "correctly" installed EI would be rare mate, there is a reason all the new gear has EI and not points. I jump on my bike and one kick it fires right up and idles beatifully, 33 year old bike that can do that makes installing an EI worth it.

I suggest you find the reasons for the "lacking power and un-even running" first before investing good money into a new EI system. Your problems may not even be connected to the points system at all.

Check fuel, carbs, jets, plugs, wiring, ignition switch, properly set points, air filters etc.

EI is good but is much less forgiving than points if you have less than perfect wiring connections and ground connections.

You won't gain any power or performance from E.I.,compared to well-tuned points system.
Your electrical system and battery need to be perfect for E.I. Even some A.C. leakage at the rectifier will cause E.I. to run badly.Some things that wouldn't cause a problem with points can upset or completely stop an E.I. system.If you lose a few volts from a bad connection or switch,E.I. won't even start.

If any of these things are causing you problems with points,they will cause bigger problems with E.I.

If you don't have a good points plate and AAU,it may be cheaper/easier to fit E.I.
The best points plates have independent timing adjustment for each set of points,and the condensors are mounted near the coils instead of on the points plate.I think these were fitted from engine number H51616,with a 160 degree dwell AAU cam.If it looks like the points close for almost the same time they open,you have the correct AAU.

Whether you have points or E.I.,you have no easy way to check ignition timing with a timing light.You need to change the primary chain cover for the later '69 onward chain cover.With the later cover,you can easily check timing with a timing light.You cannot accurately set timing with E.I. without a timing light.

Thank you All for your comments. Seems I need to get it by the mechanics to check wireing, points, jets ect. I am really appreciating your comments - even if it wasn't a simple fix buying and installing a Boyer/Panzon ei.

I'd say go eletronic, faffing around with points, and unknown advances should be consigned to the past! With the codicil that the system voltage must be dependable, so good alternator, battery etc. I'm convinced by good simple modern electrics, and they're better value than the original stuff long term

If there is any problem with the AAU and the advance curve,it would take about one minute with a timing light to diagnose that.
It may take a little longer,but no great expense,to rectify it.It's likely to stay rectified longer than the warrany life of any E.I. system.

If the timing is correct on both cylinders at full advance,you should still be making good power.
