I posted for some pulley info elsewhere but need to get some exact info from other 08 Deluxe owners if I can. I don't now if the 08 Heritages are the same. If they are then chime in.

The stock pulley is 66 teeth. Has anyone put a 65 teeth Pulley on their bike without any problems?

 

Never seen a 65 tooth pulley for the softails. Is it a new item. Also you might be going the wrong way as a 65 will lower the rpms and make sixth useless below 75mph or so.

 

Other than a Harley product, I can't seem to find anything but 65 teeth rotors. Specifically in a cross mesh laced. Once again acaseof the after market companies not keeping up with the changes I guess.
