Life is good!
Yep your right on. I started at max pressure and I'm working my way down. I'm at 25psi now. I redid my axle, with a bounce. I didn't have the torque wrench out and snapped the stud on the pinch bolts. The nut on the stud had marred from just using a wrench on it. I replaced the top two studs with bolts and lock washers. This is the third time I have broke a bolt on the bike. Probably my fault every time. Fortunately I work at a shop so I just add stronger stuff. The death wobble went from 55 to about 62 which is where it was before. I don't know if it is from tire pressure or minor adjustment to axle, but all is well.
