I recently replace the fuel pump to tank seal. When I had the fuel pump out, it looked pretty bad. I replaced the in tank return line and the rubber baffle that the line goes in to. and the rubber lines in the tank. After reinstalling the pump, I noticed that the bike would only rev to 8,000 rpm at full throttle. After noticing the problem I have replaced the fuel filter, spark plugs, and fuel pressure regulator. None of them resolved the issue. I also disconnected the power commander to rule that out. It only seems to have this problem after about 100 miles on a tank, and only at full throttle. I think I'm just going to order a pump next unless someone has any other ideas.
