I recently got a bb big bend I have noticed a few things ever since I got it. At certain speeds, particularly when I go around 25 mph I hear a very distinct rattle in the engine almost like a ticking. I have to speed up to a few mph more to get it to stop but it doesn’t happen once I do. I notice it going around 40 as well. It seems like if the engine is cruising at a lower rpm that sound will occur. Not sure exactly what the sound would be but all I can relate it to is ticking or the sound of fuel injectors?
