This is the second time using a scope so bear with me here.
Im working on a bike that has some very intermittent issues with power loss. I have yet to encounter it myself. Im currently looking at the fuel pump felt like it was the most likely issue and easiest thing to get to. Fuel pressure was great. I would be curious what you guys think of the fuel pump amperage waveform I captured. By my research fuel pump waveforms aren't as helpful as others at diagnosing but I still dont think mine looks as clean compared to the examples of others out there. Should I be concerned about this waveform?
