Bike Model = : Gt250R /2009
Hello everyone, we’re having a problem with our 2009 GT250R that we can’t figure out. The engine doesn’t respond to the throttle until it reaches high RPMs, and sometimes it stalls. I have to keep revving the engine at high RPMs.

Low compression in one cylinder ? or electric issues from Injectors or the fuel pump itself (maybe the fuel pump is clogged on its strainer?)
have you looked at those ? If in doubt , replace the fuel strainer or the whole pump assembly, then get injectors cleaned , after this, replace the spark plugs again using NGK CR8E
Report back to see if that helped ? Don’t forget to clean all the contacts of the wiring harness, so the ECU gets a clean signal for all sensors attached to the bike, the Sentec & Daewoo ECU’s don’t respond very well to electric faults , so make sure the harness is good too!
