[QUOTE="RaYzerman19, post: 1161967, member: 18388"] The G2 tube will help some, and the PCV will smooth out all the lean conditions to eliminate hesitation and stumbling from low rpms on up, and can be programmed to provide more power (at the expense of fuel economy)....... however, none of that addresses the fuel cut-off that occurs when you roll off throttle to 0%. This occurs below a certain pre-programmed rpm (I think 4500 on an R1, don't know what the FJR is)...... so when you roll off to 0, the fuel injection is cut off, no fuel. When you roll back on, the system must 're-wet' itself, thus the delay. One tip might be to alter your technique, i.e., downshift to a lower gear into aggressive corners, roll off but roll on a slight bit of throttle as you go into the corner, then the hesitation will be gone as you accelerate out of it. I know one guy who slips the clutch as his technique, but that doesn't somehow appeal to me. I would get the PCV even with Fuel Moto's regular map, at least it will fix lean conditions that cause stumble at low rpms, particularly from 0 to say 3000 rpm. That in itself is what has made PCIII or PCV users much happier. [/QUOTE]
