I have an 08 Kawasaki brute force 750, I can not get it over 7 mp. When i open up throttle it try's to day. I replace spark plugs,coil packs, checked fuses and relays. Thought i may be a fuel pup issue. Took fuel pump out replaced sock that was completely clogged up. Put fuel pump back in bike, now the bike want start. It try's to start for about 10 sec then it dies. let it set for ten min dose same thing. I have checked rollover switch its fine. The kill switch is off. any ideas? I plan on checking PSI for 40 this after noon of fuel pump.
