Rear pulley teeth count

Hi guys,
Does anyone know what difference 2 teeth makes in a rear pulley. My (ruined) stock pulley (2011 fxdf) is 64 T and I've seen one on HD that is billet 66T.
My stock one sheared off and wrecked itself, my custom wheel and damaged rear wheel fork (swing arm).

Two more teeth on the rear wheel pulley is going to increase the final drive ratio and your cruise rpms by about 100 rpms at say 70mph; round numbers, YMMV. Additionally, you will need a longer belt; pretty sure that the OEM belt would accommodate one additional tooth but not two. Best bet is to return to OEM tooth count.
