Orbot Counter Balance

[encaprodney]

Derek, according to HOS the main change to the current style counterweight assembly is the bearing itself. It is a better make and quality. They have also changed the amount of weight on the counterweight plate itself. By reducing the offset weights it gets slightly more RPMs. The mounting of the bearing on the counterweight plate has also changed, however I don't believe that has any affect on the performance, it just makes replacing the bearing easier. Another change is the shaft support spacer behind the counterweight assembly.
I hope that helps...
