    Default IG system for 77 RD?

    Looking to upgrade ignition system on 77 Yamaha RD250.
    As it is street driven, I assume I should go with MC-3.
    But there's ATV Banshee kit, which is desigened to operate on 2 stroke, and Banshee is very similer to RDs. What is advantage and disadvantage on each kit? Also, I would want to replace points. Is there "universal" pick up kits?

    You could use the MC-3 ignition and drive it off your points. It will give you hotter spark and a two step. This is the only unit that will work at this time. We are working on a universal unit that should be ready in the next few months.

    Thank you

    By the way, I have 6A 'box for cars lying around.
    Can I use this unit for bikes as well?
    What I see from the catalog is that spark duration and amparage requirement is different on 6A and MC-3.

    With these units you will still need to make a triggering system to run the units. Both units will take a little work to make the run. They will give you hotter spark and build in two step.

    Thank you very much for your support!
    I will try triggering with stock points, for the time being.

    Thank you very much for your support.
    I will try to use stock points to trigger the unit for now.
    Please let me know if you have any reccommendation for triggering system. (magnetic? hall-effect? Optical Triggering?)
