Does anyone have a friction plate and a caliper with which to measure it falling readily to hand? I'm looking for the OD of the plate at the outside of the drive tab and the OD/ID of the friction material.

I've already pulled the clutch out of my YZF250 (5.425" tab, 4.768" friction OD, 4.145" friction ID) and I expect the 400->450 have a little bigger OD plates. If so, I'd like to find out the bigger bike's numbers within a reasonable accuracy.

I'm looking for donor plates to possibly build a new clutch for one of my vintage thumpers (definitely not a Yamaha).
