Hello all, I have a 98 Suzuki DT140 that is acting up. It starts and idles just fine, and does well at low speed. When I push the throttle past this point the motor starts to hesitate/jerk and won't go any faster. This is a fuel injected engine. Does this sound like a fuel delivery issue? It sat for about a month before I put it in.

Put in new gas and injector cleaner and ran it for a good while. still won't get up on a plane and won't go past 2500 rpm. I'm going to change out plugs next and see if it improves.
