Stutters when down shifting to break

[Eternalydamd]

I've noticed when I'm in third gear and let of the clutch it stutters sometimes, doesn't do it all the time, just some times. Has anyone else had this issue?

Can you describe the "stutters" is it the clutch you feel or is it the engine RPM... going up to third gear or when you down shift to third? A little more info would be a big help in diagnosing the issue.

I've only noticed when going down into third, and it's the engine's RPM

Hmm. Do you mean like the engine is misfiring?

Or perhaps like it's skittering the rear tire? I can imagine that a mismatched rev on a downshift could skid a tire a bit?

It might be a miss fire, the engine cuts down to super low RPMs then back up and the entire bike stutters, has only happened a couple times, and they were hundreds of miles apart.

This is a new one (to me). There are many reports of our bikes "stumbling" a tad when cold, and taking off in 1st gear, but I don't recall hearing anyone report this phenomenon when warm and in 3rd.

Any info you can share about it's service history? Last plug change, etc?

As I read it, the OP is saying the problem is when he "Engine Brakes" with the transmission in 3rd gear. Wouldn't an ignition problem, like fouled plugs or bad wires, show up when you're accelerating??? I would think it's an ECM or sensor problem.

Last full service (spark plugs, all fluids, air filter...) was about 8,000 miles ago (getting oil and final drive oil replaced today as well).
