Do any of you L5P owners notice a tapping or knocking noise that is synched with engine rpm when you let off the accelerator and coast? It only seems to happen between 1,000 and 1500 rpm. My 16 LML made a similar noise sometimes, but this L5P seems to do it more. It's not the typewriter tick, that's for sure. I'm probably just paranoid about the new platform, it's probably nothing. I'd still like to know what causes the noise.
