Strange noise on RXPX
I went out riding today and noticed a noise. While riding, not at idle, but anywhere from 2000 RPM on up, I notice what could best be described as a rattling of sorts coming from the ski. Maybe even like rocks being shaken in a box. It sounded like it was coming from the engine compartment but it was hard to tell. The ski has 5 hours on it and is stock other than the R&D grate that I installed yesterday. No cavitation, and other than the noise, the ski runs great. Before I installed the grate, I had a best speed of 68.9 hitting 8180 RPMs. Today, I was all over the rev limiter at 71.6. And speaking of the rev limiter, when you hit 8200, how much should the limiter back the ski down? I would loose 20-60 rpm each time I would hit 8200.
Just to be safe, I was already planning on changing out my washers but do I have something else going on?

Thats what the x's do when they hit the limiter.

The washers would not be bad and do those rpms.

When the cage on my charger bearings broke apart it caused the wheel to touchdown and caused a similar noise to the one you are describing, but performance was still good. Not an hour later it completely failed and the charger wouldn't make boost.
This seems rare so may not be your problem, but pull you hose from the charger to the cooler and inspect for a gray dust which would indicate your wheel is touching down.
