It's kinda funny that some would find a negative in something that most find to be a positive.

With the Brison singles, you have a choice of a mechanically advanced or computer advanced ignition. Those who use them understand that the mechanically advanced arrangement provides a smoother transition from low to high throttle and a superior mid range.

The only reason that Brison provides a Syncrospark ignition is because somewhere along the line the misinformed and easily led began believing that the computer advanced method was better. Not true. It was nothing more than good advertising hype to lead consumers into believing that a new and different engine was better than the ones everyone had, and are still, using. That's not to say that an auto advance unit doesn't work well. You can't beat them for a twin, but on singles they are prone to issues that the mechanical can never be.

There is nothing on the mechanical arrangement that needs to be adjusted by the user. It's just something that sits there and does it's job. If kept relatively clean it will last and perform as long as the engine will, which is a very, very, long time. So there is no reason to purchase cherries when lower priced apples perform just as well, if not better.
