Grinding sound from transmission?

[minieggroll]

Hello,

So while I'm in 2nd or 3rd gear I heard kind of a grinding noise coming from somewhere in the transmission/gearbox. I haven't been losing any power or anything, just a rattling sound during lower rev range. My drivechain has correct tension and I'm not sure what it could be.

I'm wondering if my clutch isn't fully engaged when I'm riding. My clutch disengages fully with about an inch before I fully squeeze the clutch handle and engages very close to the fully released handle.
