S&S tuning pins...

[Joseph Garrett]

Ron,
If Plate Bushings were made correctly, as they originally were designed,
then they would definately have an effect on the overall torque. I
personally can varify this with past rebuilds, using plate bushings made out
of pin block material. And with the system I have devised for preparing
regular plate bushings, prior to installation. This system retards the
failure rate considerably.
Regards,
Joe Garrett
