Update
dropped the FDR to 4.1 tonight and gave it a run. Motor got to 175. I tore the motor down and couldn't see any obvious issues. Motor is clean, timing board looks ok. No damage. Bearings are in great shape...like new. I did notice the rotor was out of balance. Tried another stock rotor and the temps still got to 175. Put in a Novak ss and temps dropped all the way to 105. I'm really leaning towards timing board but I was hoping to get more opinions here. The motor is still very strong and is giving me some great lap times. It does go flat around 160 though but I expect that.
Thanks.
