Has anyone checked into the lighting ignition Service Honda offers for the CR500.
The CR250 & CR500 have different part numbers for their ignition systems, but if someone would take the time, I bet it would interchange on to the TRX adapter plates.
You look at a CR500 crank, the flywheel side is the same as a CR250 & the 500 stator plate, it has the two bolt mounting just like the 250 stator plate.
Ignition switchings not that big of a deal if you know the basics of things. Just a matter of the flywheel or rotor taper inside matching the cranks taper & the fabing up of a stator mount of some kind.
Shucks, if one wanted to, you could take an ignition system off a chain saw & make it work long as the timming is set at the proper time.
An ignition like that would be a whole heck of a lot simpler than what we are dealing with now, just would take a bit of time to figure it out.
