The fully CryoHeat processed kit with micro polished connecting rods and crank, the BC stroker kit for the Can-Am X3 engine Is by far the strongestis by far the strongest rotating assembly that also makes the most power. The CryoHeat parts significantly hold better dimensional stability, greatly improving sheer strength, and wear resistance by over 250%. The micro polishing helps by significantly cutting down the windage in the bottom end of the engine and decreasing the oil sticking to the parts were not needed ultimately waiting them down, causing more drag and changing balance of the rotating assembly. The combination of the two proprietary processes will help the engine parts operate cooler, last longer, and make more power. This platform incorporates a 73.5mm (+3.8mm) stroke in the OEM crank pin configuration. This 73.5mm stroke along with the stock 74mm bore turns the ROTAX 900 into, essentially a square engine which delivers the perfect balance of speed and pulling capability. The stroke increase also builds full boost approximately 2000 rpm sooner than the stock (69.7mm) stroke. Depending on bore size that you decide, the BC kit will take you up to a 948.35cc with stock 74mm bore, 974.17cc with 75mm or 999.60cc with 76mm Darton sleeved case configuration. As usual, each BC kit features your choice of CryoHeat processed custom BME, CP or JE aluminum forged pistons, 9310 alloy wrist pins in .190" minimum wall thickness, locks and complete ring pack.
