So will this be usable now with the rest of the bike stock or is this just the first step and now we get into the fuel mapping, etc.?

Hi Scott,
What we have now will be usable with the stock bike.
However, it will not be optimized, because the flow curve favors more lift of the valves to get what the porting job gives. But if a person wanted to put it on the bike the way it is now, it would still give some improvement. It's just that the cams are so low lift that they just can't get the valves open enough to get good flow.
I would suspect that if the ported head was used the way it is, with stock valve lift, the stock ECU would have a good chance at being able to adjust for its needs automatically. But I think it would give only a mild power boost to do that.
So, the next step is to get some valve lift.
And then a 535 piston for more bore, crown clearance for higher valve lift, and establishing a proper squish distance.
And then the performance ECU.
We have plans for each of these subsequent steps.
The best news that I got is that it appears that this mod should be quite affordable, and includes our Ace valve gear with the beehive springs.
