Piston weight 388gr. Piston pin weight 97gr.  Head type: Dome \/ Dome -47cc.  Compression height 1.285\" \/ Bore 3.4980\".  Stroke 4.250\".  Rod length 7.440\" \/ Cyl. length 5.330\".  Comes with T6 heat treated 390 Hypereutectic cast pistons with 16% silicone levels which enables running a very tight clearance for longevity and hardly any piston noise.   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.\u003c\/p\u003e","brand":"Kb Performance Piston","offers":[{"title":"Default Title","offer_id":50010532118856,"sku":"944654","price":306.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2711\/4344\/files\/944654.jpg?v=1779056542","url":"https:\/\/holydeath.com\/products\/kb-performance-1340cc-shovel-pop-up-piston-kit-005","provider":"Holy Death Motorcycle Co.","version":"1.0","type":"link"}
