Fluttering in low rpms

Last few times i noticed that when i am in gear slowing down, when i get around and under 3500 rpms there is a slight sound and a slight feel of the engine fluttering. instead of being a smooth decel theres the flutter. The bike seems to be back firing quite a bit more than usual, as well as spitting flames out the ass on rapid decel down to low rpms.

I have rg3s, a PC and its been mapped. quite awhile ago when i had the tail up and idling i bumped the low button on the pc3. not sure what those buttons do, havent researched much into it. that happend awhile before the fluttering started.

any ideas as to what the fluttering and the back firing is being caused by? thanks guy and girls

Too much fuel (rich) would be my guess. Have it dyno tunned.

It's already been tuned and I haven't done anything since. What Do the buttons on the pc do? I figured it was excess fuel for the backfiring but what would cause the flutter after 3100 rpms when there's that surge, the Ebs relay?

Do you have the map saved? If you have it backed up, load it back into the PC. You might have messed up the settings with those buttons (they are for on the fly tunning) I crazy glued those buttons so they dont get pressed by accident. I suggest you do the same.

The EBS makes the engine do a kind of fluttering thing during decel....maybe that's it? Normal characteristic.....but the flames are another thing altogether.

I used to be fast....now I just dream about it.

I dont have the mapped saved, i just emailed the previous owner to see if he has it. At 3100 or so rpms it does that lunge thing but the fluttering sound and feeling is new, as in the last 200 miles. Damn, i wish i knew someone else that had a MV! Urg!
