Might want to cut that diameter back. I do not have all of the math with me, but if you were to reduce the size of the cylinder, the travel would be less.
You might want do that and then see what you have. Are you using Tilton?
If everything starts to looks good and you are still over shooting, you can adjust the stop out to limit your travel.
You might want 1/2 inch for your clutch setup.
What you do not want is over shoot. That will have the fingers in a position that at high RPM it may fail to release.
Yes, I have a grade 8 pin at the fork creating a pivit point for the rod. Then I have the rod just touch the cup in the slave.
Hope this helps.
