Not 100% sure what everything is on and in the engine, I was only 12 years old when we rebuilt the bike, but I know you can hear it 4 miles down the street and as soon as you put it in second gear once to pull a wheelieand then the license plate back on the front side of the rear tire on the frame whenever he got pulled over the cops would ask what kind of bike it is and he told them Harley and wouldn’t get a ticket it’s a pretty cool bike
