Gen 2 Problem Fixed

[ky busa]

My 2011 busa had been running weak in the higher rpms wouldn't pull to redline stop at 8,000 rpms or before ran great when riding normal. Checked fuel filter & cleaned it tank was spotless no rust check volts(charging system) it was good so I bought a new oem fuel pump assy. problem solved pulls like it did when I first bought it I saved my old fuel pump assy. never know someone may need it. The original fuel pump lasted over 40,000 miles before getting weak hope this post may help someone in the furture.

It might have been the filter plugged up, so the pump itself might be fine. I did the filter bypass and installed an external filter, and I got the same power restoration. But I spent $20.
