Anyone have one or dynoed a bike with this kit?
Ya, run that by Wurk Truk!S&S says you can't bore the stock cylinders to 3.927" because the stock cylinder liner material is weaker than S&S. S&S uses a different material for the liner so I can safely be bored that big. Stock cylinders are fine to be bored to 3.875, but not 3.927.
