Run engine until operating temperature is reached. Shut engine off. 2. Disconnect the positive lead on the battery, then while still disconnected, press starter to discharge remaining electricity from the capacitor, wait for approximately 15 minutes, and then reconnect the battery. This will reset the TPS on most motorcycles by itself. If not, go to step 3. 3. Turn the ignition key on (or push starter button briefly 2012-13 and listen for the fuel pump to charge up, do not start engine). 4. Turn the throttle to full stop and then back again. 5. Turn the ignition key off (or wait for efi to cycle and shut off 2012-13), and then turn it back on again (2012-13 see #3). 6. Start the bike without touching the throttle. Air Bypass EFI Adjustment 449/511 This is the big brass screw high up on the side of the EFI body 2 ¼ turns out (+/- 1/8th of a turn) should put the minimum air bypass back in range. Notes: Re-flash ECU with BMW map set #3. Most dealers can do this and solves the majority of the issues on here, poor starting/flame out issues. (TE/TXC) The brass screw is the only screw on the throttle body that should be adjusted. Add +1/8th turn if engine fails at low idle due to aftermarket exhaust. Remove the EFI cable cover off the side of the EFI main body and check if all the cable adjusting screws are tight and that the cables wind around the cam correctly through its full range of movement. While you are there you might as well check for the correct cable backlash/free play. There is a section in the owner’s manual which describes this. 2012-13 models require clutch lever activation in order to start and discharge the capacitor. Check battery, engine and frame grounds. - SAM511/Tinken
