just my two cents after doing about 20k with this pulley first of all quite a lot of fun but like a lot of harley stuff trying to set it up was a pain any how some how the whole bearing or some thing moved to the right about 5mm dont know what that is in inches so i put the original wheel and pulley back uses less fuel and sits properly but for a cheap upgrade i can recommend it pulls like a train 

Would help if everyone new wtf your on about  maybe a bit of explanation on 

I assumed he's talking 70t vs 65t rear pulley. 

Haha exactly!
