[QUOTE="davidd, post: 24979, member: 1177"] As I understand these electronic ignitions, they either make a spark or they do not. The "fatness" of the spark is not really relevant. Like Tim, I have used the BT-H for racing and it has worked well. I would strongly urge any Vincent owner to have a stock magneto in perfect repair sitting on the shelf while they have the modern ignition of their choice on the bike. The original problem reported in this thread does not sound to me like an ignition issue if there is spark as reported and the bike is not continuing to run. I would install the original perfectly rebuilt magneto to see if the ignition is the true source of the problem. I will say that I am unhappy with these modern ignitions in that they cannot be checked for performance. We all understand how to make a mechanical magneto work, at least in theory, but the electronic components are a mystery to the average or above average mechanic. I have mentioned in another post on BT-H that I think it is best to check the timing with a strobe so that you understand where full advance is in relation to the timing pin and the backlash in the system if you are concerned about correct timing.
