Sooner or later, somebody's got to put a Pressure-Gauge in the fuel-line between the Fuel-Pump and the Injectors and an Ammeter in the Power-Wire going to the Fuel-Pump. Then maybe we can isolate this whole problem. Right now, everybody's just shooting in the dark, without a clue. The only thing that seems consistant at this point is that it SEEMS to be heat related. My Fury has NEVER coughed or stuttered, even though I've ridden it on some pretty hot days, so I don't really have a sense for the problem you guys are experiencing. It's happening often enough to enough of our riders that there HAS TO BE a common denominator.
The entirety of the road of Human Evolution is littered with examples that failed. Now, you're all that's left. Scary, isn't it?
