Note: Top compression ring will need additional clearance.
See instructions.
Note: Around 30% of stock 1340cc Shovel cylinders may present a problem in combination with the location of some of the oil return holes since KB pistons have a wider piston ring pack for better piston stability in the cylinder.
In these cases the oil return hole must be re-located (lowered) to avoid excessive oil consumption.
