Thanks for the replies. It seems all agree that the oil ring in the pin hole is not an issue. To back it up, I talked to three “name” piston manufacturers that agree with you guys.
I have found cylinder walls that I don’t like, and oily valve head/guides on the intake.
I have finally got the crank out and am waiting to get some measurements.
So, you guys don’t have a problem running a 4.5” stroke on the street?
After reading posts on here about cranks, I am a little hesitant to let my Callies go!
