Last night I decided to finally start work on replacing the camchain in my CBR1000. After removing a seemingly endless pile of plastic, rubber and metal bits, I was just about to unbolt the upper camchain guide when I dropped the socket I was fitting to the ratchet - down the camchain tunnel. It was wedged in too tightly for my magnetic pickup tool to retrieve it, so I went after it with the claw, but only succeeded in dropping it even deeper into the motor. Hopefully it'll turn up when I take the sump off. :-( BTH
