nevermind after changing every single part on my 636 turned out to be my ground wire from battery if any one has bogging prob try replace wire and sand connections the battery has two grounds helped me

 

my 636 did this cause the fuel pump wasn'y making the right pressure

 

After replacing the entire ECU,fuel pump, plugs... I put on new Throttle Bodies and that fixed it..

 

What were the symptoms of your problem>??
Mine just recently wont start. Cranks all day but no start. Traced it down to subthrottle sensor on throttle body assy. FI light showed 3 longs dashes followed by two short ones. Manual states either im replacing the throttle bodies or ECU....Ulgh Oh and I think im not getting fuel pressure or something cause my plugs dont smell like gas at all...

 

At 11:30 the bike was bogging HARD, like almost turning off. At the time bike was not giving me any codes.
