It’s a 2F. Igniter and coil most likely came off a 70 series. If you can read the part numbers and Google them that will point you where it might have come from. It is a fairly common upgrade to swap from the original. If you want to send me a PM, with your phone number, I’ll give you a holler...

There are a few other classic BMW owners with cruisers in their stables. There is a really cool build thread I can’t remember who’s right now. He did a great restoration on his cruiser, sold it, did a few bmws and then bought his cruiser back from the guy he sold it to like 3-5 years later...
They’ve got a pretty cool showroom local in Coppell, TX just off 635. If you haven’t been by I think it would definitely be worth a visit.
