Why does my Triumph Bonneville not start properly?
The fact that the fuel is six months old will not seriously affect starting, since when I previously fixed the starting by clearing the carbs and fitting a new ignition coil, the bike started fine on fuel which was nine months old. The only other thing which I can see is that the spark does not appear very strong.
What kind of ignition system do you need for a Bonneville?
In principle, any electronic ignition system can be used, providing there is a trigger pulse supplied to it and the ignition HT coils used with it have the correct primary resistance to match its electronic characteristics. Click to expand… Thanks for the link, Half Ton.
Why does my Bonneville EFI not turn on?

Why is my triumph 05 Speedmaster not starting?
Thanks for that chap. Very useful and most appropriate at the moment as it seems my 05 Speedmaster has developed an ignition fault after being in the garage for a couple of weeks. Fuel on, switched it on, pushed the go button, engine spun over the rev counter went round to 7000rpm and stuck there, no brum brum.
Are there any problems with the triumph starter?
All the wiring seems sound and no obvious faults apart from some muck. The igniter checks out, there is a resistance and the air gap is within tolerance. The LT side of the coils, HT leads and plug caps all check out, (resistances within spec’s), but nowt on HT side? so there’s one possible?.
What should I do if my Triumph bike won’t start?
— Maintain battery in peak condition. — Follow proper starting procedures.
