How difficult is it to remove and clean the fuel injectors on a 2010 F4?
 
Bike is lurching and stalls sometimes at idle.

removing injectors?
 
Sequim-MVF4;
remove the tank
remove the fuel rail.....try to keep the injectors in the throttle bodies....if they stick it the fuel rail, GENTLY pull on the body of the injector to remove it from the fuel rail

DO NOT BEND OR PULL ON THE WIRES CONNECTED TO THE INJECTORS OR THE PLUGS

now with your thumb, press down on the wire clip on the top of the injector plug, where the curved cutout is......if the clip is on upside down, hooks on top, remove it with your fingernail...now remove the plug....and the injector

cleaning them is a job for a professional
i use RCEngineering, Gramps invented the testing machines and taught Honda how to inject cars

I made an Injector cleaner from a Gunsons Easybleed used on my Duc 916 injectors. Worked a treat on them.
