Crank Runout Help Please

The crank shafts on some bike can get knocked out of truem0n s0me bikes that are ridden very hard or due to some other causes. One wheel is jot in alignment with the other, hence the expessi0n, the crank is twisted. I'm not saying that that is your issue, but if you have exhausted allmother thoughts, it might be amnew path to travel in your investigation.

I applied the pressure to see if the bearing was loose. As I said I was looking for something out of whack that could cause a knock. It was knock free until I installed the S&S kit as described in the original post. I removed that kit and went back to a 103 set-up. The knock with the S&S kit was clearly in the top end. I ran that kit 90 miles then removed it. When I went back to 103 there was a different knock that seemed to be in the bottom end so I went looking and started with the run-out indicator. I'm wondering if with the bearing that loose could the crank be moving up and down in the bearing causing the knock.... The engine has 36000 miles on it.

I didn't put pressure on the crank bearing and then measure the runout. It was two separate operations. When I put the pressure on the bearing I was trying to determine how much movement there was. I wasn't turning the crank while putting pressure on the bearing.

I highly doubt that is your knock. I also don't understand how you put pressure on the bearing - it's in the case. If you were prying up on the shaft that passes through the oil pump and cam plate and read .012", I wouldn't be concerned.
The pictures are not really clear.
