3 bolt or 1 bolt cam?

there is a special sprocket you have to get to generate 4 pulses per revolution of the cam versus 2 pulses in the older model. Surely someone already is marketing the 3 bolt 4 pulse cam sprocket.

That must be what I saw Lingenfilter selling on ebay.
They do make a swap sprocket kit too.
