SmartFire

Personally I would not use any ignition with electronic parts inside the points cavity. I do a lot of cross country riding and heat is often an issue.

Even when the electronic parts are designed for high temperature use, they do fail simply because of expansion and contraction of the circuit and vibration of the silicone junction -sooner or later.

I have fitted one SmartFire unit. It worked fine when installed and the only problem I am aware of was when he pressure washed the bike and got water in the control box.
I did not notice an increase in performance over the Boyer that it replaced.

Hall sensors used in high temp applications have a high mortality rate. See the problems reported by BMW riders. They did not see a lot of failures of the silicone junction itself but more so the mounting and wiring to the component.

It is likely that the majority of Nortons see much easier use than mine and many people will not encounter problems in the foreseeable future with any of the systems. Jim

I will assume that it fair to say that because the Altair uses the same trigger plate (with Hall effect) that you would not use that one either?

I have never heard of anyone having issues with either of these units (Altair, Smartfire) in this regard. And as it compares to other systems in this price point, and without mentioning any names, and as it pertains to "mortality", the difference can be said to be profound.
I do not mean to sound bias, just stating what I have read over the years.
