The new alloy barrel castings posted previously have now been completed. These took a lot more work than estimated. The key feature of this design is tappet access incorporated into the barrel. Stock barrels on the V twin require tappet adjustment through the rocker covers, this design retains the quick access. Castings were bored to shrink-fit cast-iron sleeves. Sleeves were bored and honed after installation. Both cylinders are now complete and ready for fitment.
