Spyke, starter ring conversion kit. 102T to 66T 94-97 Big Twin

Converts from 102 tooth to 66 tooth. Consists of a starter gear and starter ring gear. Can be used with all Spyke starter motors. Will convert from the standard 94-06 102 tooth to the earlier ring gear design with 66 tooth. The early 66 tooth design will withstand high torque starters, large displacement & high compression engines better than the late 102 tooth design.
