I have a 09 Xciting 500RI that I use for commuting in the hilly city of SF.
I notice that when I ride 2 up and a lot of inclines, the scooter starts to grumble when accelerating from 0mph. Almost sound like something rubbing loudly. Anyone experience that?

I can only suggest opening up the cvt case, a couple of bolts, size 10,and have a look inside. Lots of black dust = belt probably needs replacing. Move the variator and clutch in various directions, not only rotational, and check if there is a lot of movement.
Now that i have written this, I am leaning toward the clutch pads or mechanism, but I admit, I am guessing.

Inspect belt. Inspect clutch shoes, buff with a brass brush if glazed over, replace them all if one is cracked. Clean up inside of bell housing with brake cleaner. If you have the tools, disassemble the rear pulley and re-grease the sliding shafts and bearings. Do not attempt to clean the pulley belt contact surfaces with cleaner or grease cutter unless you are sure that it won't drip down onto the drive shaft, and that you can clean it all off afterwards (i.e. you have the pulley already disassembled). Do NOT overlubricate, since it will fly outwards and potentially onto the belt or belt friction surfaces.
While you have the case open and the belt off, it wouldn't hurt to clean up and relubricate the variator as well.
