Sounds good. I take it there is no advantage to the later style ignition system then? I like the idea of it not being adjustable though, so there is one less thing to adjust and troubleshoot. But I also hear that the EZL's are fragile and expensive to replace.
My 500 currently doesn't have the switchable transmission. Is the wiring easily swapped over?
