Welcome, sorry your experience has been unpleasant with your EFI America. I also dealt with a snatchy throttle but I wonder about this,
I do not want to sound critical and maybe just a bit more information might help.
By "constant stuttering between 2000 3000 RPM" are you saying it stumbled as you would accelerate/decelerate through this range or were you trying to cruise at that RPM?
Just asking. That is a range I pass through from start and may re-enter on deceleration but would not hold constant throttle. Would feel like I was lugging the engine as being so far down on the power curve of the motor. May also be staying at or very near the open/closed throttle operation transition point with such small throttle opening making it far more of an EFI issue than for carbs.


Hi Matty, you don´t sound critical at all.
The snatching issue is presente in all EFIs bike, thats a fact.
What you just said about the transmision point of throttle is absolutely right.
What happened to me was like a little hesitation or stuttering when I was cruising al 2000-3000 REVs with a fixed trottle position or decelerating/accelerating a little bit. Not happened when I roughly opened gas. I know it's a matter of fuel tables of the map and around those REVs a TPS there is a transition between those tables, so here is the problem. Obviously, this didn't happen on higher REVs.
I like to travel at low REVs, and cuoldn't achieve this on my former America, unlike I had to shift down and rev a little more the engine to ride at low speeds, and I don't like this kind of behavior.
Thanks!
