Tuning - 1975 Rally 200 VSE1T, Malossi 210

Hello,

I would like to upgrade my Rally 200 (all original except for Femsa replacement CDI).  I am considering the Malossi 210 Road kit (Art.Nr.10200000).

What would I need to do about the ignition?

1) Changing the crank to a Femsa one (Art.Nr.45171000) and then only Malossi 210 kit
or
2) Changing the crank (for example Art.Nr. 45021000) and then Vespatronic/Parmakit and Malossi 210

Thank you!
Tom
