I have just got myself a iron883, just wanting to know what everyone thinks about the best way to go about getting more punch out of the bike. After coming of a a big bore 96 road king.

High comp pistons in 1200 cylinders, with cams to match will blow away most big twins 

Hammer Performance 1275 kit.

Thank you all, I may only go with a stage 1 upgrade because this bike is not a keeper just something to get me around town. Until I find my next ride
