Having some issues with my 02 f4i, wants to bog low end but as soon as I give it some throttle above 5k it works perfectly fine. Idle is kind of weird. I’m thinking ignition coils espically after replacing plugs last week. Can anyone give me some ideas??

 

Any codes being displayed? "FI" light on?

 

Hi MrFerrell,

Please take a moment and pop over to the new member area to introduce yourself to the forum.
Where are you from, how long have you been on two wheels, what bikes do you have etc.
We also love pictures.

No F1 lights on plugs are good coils are good. I’m thinking maybe a fuel pressure regulator. I’ve got one shipping right now!
