Material gets removed from the backside of the flywheel although generally the
machinist will lightly face the clutch disc side. Material removed can be much
greater than 4 lbs. Seem to recall that mine was taken down to 15-16 lbs.

Content-Type: text/plain; charset=us-ascii; format=flowed
I have easy access to the flywheel right now and would like to have it
I understand 4+ pounds can be removed but it isn't obvious to me or my
mechanic friend where to remove the
metal. Can anyone here elaborate?
I tried to locate my copy of Kastner's Comp Prep manual, but I've misplaced
it (I guess because it is so small).
If there are detailed instructions in there, can someone fax it to me?
Background info: My plans for this engine are 9.5:1 CR and GP2 cam (ie,
street use on California pump gas).
Thanks in advance,
