Hi, have a -68 Primavera 125. Flywheel got loose and damaged the crankcase.
Now I was planning to change to electrical ignition at the same time.
I have an old Polini 133cc kit and a reed intake+ 24mm carburator on. Crankshaft now is Polini modell?. Opened crankcase to fit intake. Exhaust is a Polini.
This parts are from 1994, so not the latest stuff, but still ok.
Can you guys help me out, as there are so many different versions of all things...
Heard I should go to a bigger shaft dia for the flywheel side, 20mm?
Would be nice with some inputs, what do I need to get?
Ignintion, new sealings, gaskets, crankshaft, bearings is clear, but the types???
