Speed: I can do 55mph comfortably. After that she begins to vibrate.
Mileage: 63mpg. Mostly city driving.
Bolts: Everything seems to be tight so far.
Other issues: At higher RPM, in 1st and 2nd gear, there is a pronounced khrrrrrr sound that goes away with even higher RPM. Clearly resonance related. Normally I change gear at lower RPM and never see this problem. It's not the heat shield, I drove without it to verify.
Overall: She is still opening up and getting smoother and I am getting used to her. I am keeping my fingers crossed that this trend will go on. I will love to get the noise problem fixed though, just for peace of mind.
