Off then on throttle lag 5k-6krpm

[JonesKi]

Hi all,

Hoping for some advice...

My bike following having the throttle bodies out and a ECU remap has a lag and a backfire between 5-6k rpm, but only when i come completely off throttle and then back on. All other rev ranges are ok.

I previously decat the pipe, mivv suono end can and Lars Airbox mod with a k&n filter and the bike ran mint.

I then decided to mod the flies with copperdawgs and remapped the ECU with ftecu and using dukes map pack. once all back together the subthrottle plate seized. Had them out and a good penetrating oil and a bit of acetone got them free (I assumed it must've been a rogue drop of locktite from the flies). The bike runs like a beast but if I come off throttle at high revs then back on throttle, even if I slowly come on the bike bogs, backfires then a surge of power again.... only between 5-6k maybe 7k

I changed the spark plugs but that hasnt made a difference.... also removed and reinstalled throttle bodies to ensure it wasn't a vacuum leak....

Does anyone have any advice?

Thanks,
Kieran

you need to go back to wherever you went to have your ecu flashed and have them fix the tune.
