So I rebuilt this engine completely with all factory parts. Transmission was damaged, so customer wanted to replace crank while I had it apart. After putting everything back together, everything worked great. Customer picked up bike and ran it for about two months (he uses it daily for work in crawfish ponds). Brought it back to me because it was overheating and would rev up to about half throttle and the cut out over and over while holding the throttle at anything above half throttle. Radiator was plugged. Everything with ignition tests good. I never loose fire while this is happening. ECM is brand new, fuel pump is new, injector is new, swapped TP Sensor with known good one. Fuel pressure is at 51psi at idle and its hard to tell because of vibration, but seems to drop to about 42psi while its cutting in and out at high rev. Any ideas on what could cause this?
