I have a 2009 kfx 450r , it has been running strong but as of late it started misfiring and it just bogged out on me and turned off the other day for the first time .I’ve noticed it only done it when running and riding for a good amount of time , it usually happens when im going full throttle it will lose power . This is the second time it’s done it , when it did the first time i put new spark plug on and put fuel injector cleaner in and it seemed to be back running strong . But now im starting to think it may be my fuel pump may be going bad? please help ! Thanks

Welcome to the Forum...!!!

Make sure the battery is fully charged 12.8v standard...?

Does your F.I/water temp (far left) dash light remain on of flashing when starting & idling...or turn off after 3-seconds..?

After the motor warms up is it hard to start...?

It could be your fuel pressure issue usually the strainer inside the pump is dirty/clogged...see pic
