Crashed YZ450F Motorcycle Repairs: Fuel Pump, Stator | Partzilla.com

AMA Supercross pro Scott Champion crashed it. In this video we&show you how to fix it. Scott competes in the 450 class of the AMA Supercross Series, and in Tampa he took a pretty big impact on his practice bike. So, John is going to keep this dirt bike for a couple of days to tackle three separate repairs. First, John will show you how to replace the fuel pump on a YZ450F. Scott’s team replaced the unit and it worked fine, so that isolated the problem to this particular fuel pump. As it turns out, the impact broke the fuel pump, so we’ll get it swapped. Then, we’ll get after replacing the crankcase cover, which was cracked in the accident, and then finally we’ll replace the damaged grip assembly on the YZ450F.
