Default XR lurch when almost stopped.

I have a 2010 XR with 15k on the clock and I love it. It has performed flawlessly, but since day one I've noticed that when I am slowing down, when the motor slows to around 1500-1600 RPM's there is a very noticable lurch in the otherwise smooth deceleration. It almost feels like the transmission has just shifted to a lower gear on its own. This is always bothersome but it is more than a little bit alarming if I'm in the middle of turning a sharp corner and haven't begun to roll on the throttle yet. And if the "downshift" occurrs just as I'm rolling on the throttle the ride is anything but smooth. I recently rode a 2012 XC & XR in Daytona and they both seemed to do the same thing but it was very subtle compared to what I'm experiencing. Any thoughts???

Same thing on my Vision. I believe it's in the way the fuel map is designed for it's "lean cutout" that helps burn carbon from the catalytic converters. It's a transition from ultra lean to normal, or the other way around.... It can be mitigated with a PC5.

It's the ECM shutting down fuel to comply with EPA regs. The way all Victorys run, since '08 anyway. Applying throttle at 1500 rpms is lugging the engine and it's definately not pleasant.

I have it also - think it is the slack of the belt and play in the tranny - it happens when you are no longer engine breaking - the lurch is when the "slack" goes back to forward pulling at that given rpm.

Thats what I think it is......
