no power past 5000 rpm's

went out on the 900 yesterday, everything was good, until i hit a bump and it dropped to 2 cylenders, then died and wouldnt restart. i did notice there was gas dripping from the airbox. And the plugs were fouled So im asuming the airfilter was dirty. so i cleaned it out. Any ideas on how to fix it? thanks

If it died suddenly, check your wiring starting from the coils and working backwards to the coil. Perhaps the heavy shock to the bike knocked some wires loose.
