Building a Big Bore 277UL from parts off ebay, etc. Got a 277UL Type Case, Crank & Rod, Cylinder, and dual plug motorcycle head to start. I was told it had Bosch Points Ignition. I want a CDI Ignition.

What's my options? I had a stator plate setup off I think a late 80s, early 90s 583/617 that seems to fit, but I don't have the flywheel to go with it.

Does anyone know the different Skidoo/Rotax Crank, MAG End Tapers? I know the 277 Taper is smaller than a 670s Flywheel Taper, I had.

PTO end is 30mm 1:10.

Case Halves have these part numbers:
6912960 80
6912950 80

Cylinder:
6823 760

Engine Tag Serial Number:
3306598
72mm x 66mm 268.7cc
