That looks like a nice mod. I wonder what the price is on that. I also wonder if its a swap out deal, like you send your heads in and they send you these? Also I would guess you would need new coils, not sure if you could just swap in coils from a dual plug bike but since my M900 is carbed and the dual plugers are injected I wonder if it would be an issue. I am very interested in this and if the price is not too bad I may jump on it. Maybe Chris, or some of the others tech gurus, will chime in on this.
