nice. Whats a "stage 3 upgrade" consist of?
I don't know? it's not my bike, just sharing.
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.
The kits are by engine type and some upgrade cams are (like the 585) for lower end torque, and some are like the 600+ cams for higher rpm.
