Its just not a motor tune. The tow programs will change your shiftpoints to keep the motor in the higher part of the torque curve.

Tim wouldn't that be 4000 RPM's since these are a 4 stroke motor?
ie: 1 injector squirt per every 4 revolutions. Therefor every 4000 rotations has 1000 injector events.

Am I right?

Whoa, it would be 90cc's every 2000 rev's. Remember, four cycles=2 revolutions.
Im assuming that the 90cc rating is for the whole set?

Oops I stand corrected. You are right. Every 2000.
Duh, 4 stroke doesn't mean a revolution for every stroke. Just 2 strokes per rev.
I guess them numbers bouncing in my head are getting dizzy, I know I am.
