Boring Stock Cylinders

[D-1]

How far is it safe to bore stock 114 cylinders from a 2017 CVO? Ive seen some reports that they can be taken to 4.180? but some have had problems with the spigot cracking. KB makes a 4.125 piston, or stick with 4.075 like a stock 117?

Don't do it. Buy the appropriate cylinders.
