That's good to hear. I can't seem to get it very hot either. Have you tried the darkblue rotor? (12.5mm / 6mm) Apparently it's what the guys were running at the ISTC, although with mod motors.
Here's the spec chart:

Although it doesn't mention how the performance compares on the Stock & Race rotors, you can take a pretty good guess based on the dimensions.
For the 13.5, the darkblue should give a little more RPM and torque with less midrage.
Don't know about the 17.5... it looks like it already has a fairly high RPM rotor with the large axle, but it would definitely increase torque.
I found some of these at Stormer, I'll see how they work when they get here.
