I removed and cleaned the throttle body on the 390 Duke but the reason I needed to pull it off the bike was to replace the idle adjustment screw that I damaged whilst trying to raise the idle to prevent the bike from stalling, but in doing that I caused a secondary problem which was the bike surging and backfiring. Adjusting the idle meant that the throttle position sensor was thrown out of whack so the ECU was sending extra fuel into the engine causing the surge.
Well, long story short, the bike is running better than ever with a cleaned throttle body and the idle circuit reset to the factory default.
