The bike purr's like a kitten at idle. And It runs great at the higher RPM's. It's the cruise area at the shift point's that I'm having issues. Once I shift into the next gear, if I don't continue accelerating it behaves like it's running out of gas. It's when I try to hold a constant speed in the mid-rpms that the problem arises. It backfires, hesitates and act's exactly like it's running out of fuel. When I open up the throttle the problem goes away. Also if I shift aggressively thru the gears I never have an issue. I feel like I have to wring-out the motor to prevent the problem. I guess I can live with it. But, it just doesn't seem right. I've considered the Kientech jet kit that seems so prevalent on the forum. I've also considered putting a little thicker washer under the main jet. I'm just not sure where to start as far as thickness goes.
Here's a diagram to show what jets are in play at the different throttle openings. I would clean or replace the appropriate jet.
