Your original post isn't exactly clear.You did a 60 mile ride with the petcock off and now wonder if you damaged the pump.You again started the bike with the petcock off and the pump was noisy. Seems normal performance.So now you did an additional 30 mile ride but it isn't clear if the petcock was still off or was now opened up.Pump is still noisy. Please clarify if the 30 mile ride was with petcock open or closed.Meanwhile, the whole fuel pumping system on your bike is cleaned by a huge filter up under the tank tunnel. But, the petcock itself has a tiny screen filter about the size of a 2" pencil. That screen can easily get clogged or blocked by tank debris and will then perform as if the petcock is closed. Any indications of rust or water inside your tank? Maybe time to pull the petcock out and see what you can flush away. With an old school carburetor bike, the actual fuel flow through a manual petcock is pretty slow. There is not so much tendency for debris to hit and stick on the petcock's little filter. When the bike is off, said debris falls to the bottom of the tank and doesn't get disturbed much unless you stop to buy fuel. With a modern fuel injected bike, the pump is circulating a high volume constantly, regardless of speed or actual fuel consumption rate. Think about the cycling water in your fish aquarium. Excess fuel is directly back into the tank at a fairly robust rate. So, the minute by minute flow through through the whole tank and expecially through the little petcock filter is a LOT MORE on an FI bike than a carb bike. Hence, tank debris begins to play a much bigger role in fuel flow failures (and maybe pump noise).Patrick HayesFremont CA
What is the psi of the FI system?
