Scott,

I sent this is response below to Neil a couple of days ago.  I don't think
he got it, some numbers from Boston Bob (I believe) in the archives.  Sure
would help if you or someone could confirm this info.

Neil,

Here is a mail from the archives.

The hard and fast number for all 228 MM flywheels is .970ths I have a dept
gauge with a digital read out that sits next to my flywheel grinder for this
purpose A vernier caliper can also be used to measure dept

Its common to see flywheels that are out of spec from prevoius incounters
with a mad machinest suprpising most worked without complant

Hope that helps.  Found via google search string:  ["flywheel specs" site:
gerry.vanagon.com].  You might want to repeat this search and see some other
emails on the subject.
