8.0:1 CR. Piston weight 357gr. Piston pin weight 97gr.
Head type: Dome 0.426" / Dome -30cc.
Compression height 1.285". / Diameter 3.4980".
Carrera 4.250" (4-1/4").
Rod length 7.440" / cylinder length 5.330".
Supplied with 390 hypereutectic cast pistons with T6 heat treatment and 16% silicon, allowing a very tight clearance for greater durability and virtually no piston noise.
Note: The top compression ring will require additional clearance. See instructions.
Note: Around 30% of original 1340cc Shovel cylinders may present issues in combination with the location of some of the oil return holes, as KB pistons have a wider ring pack for better piston stability in the cylinder. In these cases, the oil return hole must be relocated (lower) to avoid excessive oil consumption.
