Panhead flywheels

[Dablaze]

I am sure I am not getting something, I have a few sets of 150-40/150-403 flywheels, but nothing matching that I can ID. I have a few with the 1 1/4" outside taper (both -40's) I understand these to be 74 correct, I have a few with the 1 1/8" outside taper which I understand to be big twin 61 cube. I also have a set that looks to be too small a taper to be even 45 ci with 1" outside tapers...what would these be for?

Anyone have a spare 150-40 for a 61ci big twin?

Have I given enough info?

Thanks

Craig,
The crankshaft and rod shaft machining merge for 61" engines, there is a gap for 74" engines.
The 36 to 39 engines use a smaller crankpin with smaller tapers.

I will try to take a photo later but mine almost look like they have a tapered sleeve in them to make them a smaller taper.

I was being a dummy, maybe I should claim I was drunk and somehow part way through looking at my flywheel collection I stopped measuring the crank holes and switched to the pinion holes...

Still not sure why some of the pinion holes look bushed and some don't.

And still need a 150-40 61", lol
