I have a 98 Fatboy that I want to install a new rear pulley and rotor to match my new front rotor. Not looking to change the amount of teeth on my pulley
Just curious if there is any way figure out how many teeth are on the current pulley without having to pull the belt off and counting teeth? Is there a difference in diameter between a 65 & 70 tooth pulley?

 

I know its either 65 or 70 but guess that doesn't help much

 

It is 65 teeth. Here is a link to Ronnie's Microfiche,

Yeah I'm wanting to say it's 65 teeth with a 1.5in belt

 

But does anyone know if there is a difference in diameter between a 65 and 70 tooth pulley?
