In the past I have had problems with the Allen part of the cam bolts rounding off. So when I remove the bolts I make sure that my Allen tools are high quality with no ware. But that didn't help me this time. This is the second time that I have checked the valve clearance on my SE. This time I wanted to record the shim sizes so I could plan ahead for when I might have to change a shim. I was using a brand new Allen tool. I held the ratchet head in place. But the Allen head stripped out anyway. The bolt didn't move from its factory setting. So now I have a few months to figure out how to remove the bolt. It really seems that the 950 cam bolts are unacceptably soft.
