Sprocket Pin Purpose

[Mick Milakovic]

Just got a new, alloy sprocket from Al yesterday, and one tooth has what looks like a steel pin driven into the base of the tooth.  What is the purpose?  Is it a wear guide, or used as a marker to begin counting, or.....?

It is for "timing" your front sprocket to your rear sprocket.   joe

THE (main) PURPOSE FOR THE PIN ON THE SPROCKET IS TO SEE HOW MANY TIMES IT TURNS ON A MUDDY DAY AT THE RACES ,TO DETERMINE  HOW MANY MILES PER GALLON OF GAS YOUR GETTING,BY THE  WAY  U.S.GOVT ANALYSIS WANTS TO KNOW EXACTLY HOW TO ORDER MORE HIGH PERFORMANCE ETHANOL FOR BETTER GAS MILEAGE.
