I am restoring a 1947 FL and a 1952 FL (both to factory specifications). The 1947 model year was known for vibrating 74" overheads (as well as blown head gaskets and broken cylinders).
Because I don't want a shaker, I will static balance these flywheels, but need to know what balance factor the factory used (for the reciprocating weight portion) and what it should be adjusted to for harmonic balance in the mid (crusing) RPM range.
I am thinking that a 55% reciprocating factor should be close for the panhead and the knuckle. Any suggestions ??
By the way, this bulletin Board is a GREAT addition to this web site !!
ON to OLEY !!
