nice. Whats a "stage 3 upgrade" consist of?

Harley numbers there engine upgrades by stages. Didn't know S&S did. Well, just looked at the S&S website and they do a stage 1 and 2. Probably a stage 3 on there somewhere but I didn't see it.

Is that fuel injected. They have to have done head work too. I have a 600 cam and bored out G carb and I ain't producing 140 lb ft of torque.


I had mine dynoed it’s pulling similar numbers , xxx carb, dual runner intake, 600 cam and 2 into 1 exhaust! She is a runner for sure.
