Sthealy makes a nice flywheel weight for Ktm's, I run an 11oz on my '09 250sx.

Change the power valve spring ( very easy to do ) to the green colored spring and turn in the brass adjuster a few turns, this will slow down how fast the power valve opens and make the bike more user friendly.

The XC uses a lower comp head but I'm not sure how much you would notice that change, the cylinders are the same.
