I've just fitted SE204 cams to my FXDX and they've made a great improvement to my bike.
I was wondering what would be the next step in upgrading the engine WITHOUT increasing the bore.
I was thinking of a set of SE heads to breath better along with a compression increase and an upgraded ignition (any suggestions?).
The bike is currently running the standard carb with a stage 1 kit, Hypercharger and a D&D 2:1 exhaust.
It also has Brembo twin disc front end, fork brace, Fournales shocks and Metzeler tyres to complete the handling package.
Any suggestions would be helpfull.
Have you thought about a 42mm Mikuni pumper ?
Also fit a Twin tech or similar adjustable ignition.
Had it dynoed yet ?
