Hi I'm new to this site just helping a fellow friend. He has a ironhead engine can't tell what year it is vin number starts with a cahf kinda weird and here is a good one. On the case there is no spot for a generator AT ALL! The hole where generator should be there is none just flush aluminum and no there is no stator in the primary we are at a loss trying to figure this out.

 

Pictures?

 

It is probably running a magneto.

 

Something specially built for competition? See if you can send the engine numbers to the Harley factory and see what they say?
