The shaft is forged with a full counter that extends the stroke by 5 mm.
By combining it with a special forged piston, it is possible to increase the displacement. A forged full counter with a 5mm longer stroke is used on the shaft.
By combining it with a special forged piston, it is possible to increase the displacement.
Setting up a connecting rod bearing-aligned kit We use the Competition Bearing Series, developed in technical cooperation with ACL, an Australian company with a track record of supplying genuine parts to numerous automobile manufacturers, and set the bearings in the stroker kit with the clearance adjusted to 0.040 to 0.060 mm in the engine assembly room, where the room temperature is kept at 20°C.
This eliminates the need for customers to take measurements and allows assembly to be performed immediately after purchase.
