All good advice, for sure. Your problem is likely one of those mentioned, but if you end up needing an oil pump, look at s&s hvhp. It's like magic to an evo. Runs better, looks great. Ain't cheap, but it has made mine Idle smoother and run cooler. Take the time to do it right by removing the pinion gear and centering the pump shaft. This eliminated a lot of engine noises I had just accepted as "Harley". Good luck... |
