I was just thinking yesterday there hadn't been any TB Q's lately. The Thermal Robert (as dubbed by Cheap) should make it so your temp guage sits right in the middle. Mine gets to the top of the screw in the center if it is really hot, and rests at the middle of the screw usually. So, If you're saying you have a TB and the needle isn't coming up to the middle, it ain't working.
On the Gen2 bikes, the doohickey is better, not great, but I would guess adequate, but the springs are jacked. My spring was floppy loose. So, you need to get in there with a torsion spring (preferabely) or a better spring. If you aren't poor like me, put a new doo in. Eagle Mike does make nice stuff. If you're watching your wallet, change the spring.
