Can someone tell me the difference between these three models of compensator I'm seeing online? I just purchased a 630B-67 on eBay and I want to make sure it'll fit my ride. Thanks!

630-67K
630B-67
630C-67

 

The original one was the 630-67K which then became the 630B and finally the 630C. They are all made to fit your ride, with the "C" being the most recent version.

 

Any idea what changes were made between the different models?

 

After reading their pdf's about each model it appears that the spring cup assembly and the motor extension shaft are different between the B and C models.

Buy critical parts from Ebay, take your chances.

 

People. They have a phone number. Call them on Monday.

One could compare the differences in the instruction sheets.

630B-67 to 630C-67 show that the Spring Cup Assembly and the Motor Extension Shaft have been revised to 624-67B and 622-67B.

630C-67 to 630D-67 show that the 34 Tooth Comp Sprocket has been revised to 621-67B-A.

I recall reading a post from Mark @ Baker stating that they changed the heat treating on it and it was actually changed in REV C, but the instruction sheet was not updated.
