BORE UP Jupiter Z 145 CC (PISTON 58,5) Harian AUTO LIARR ‼

#DailyBoreUp Boring up is increasing the piston diameter from a small one to a larger one. Some motorcycle manufacturers provide special pistons to replace the original ones with larger sizes, commonly known as oversized pistons, which have a maximum bore increase of only 0.3 mm. Other manufacturers don't offer these oversized components, so if you want to bore up, you'll need to use other motorcycle parts. For example, on the Jupiter Z 110, the standard piston is 51 mm, but using a 58.5 mm Piaton increases the cc to 145 cc. To calculate this, we use this formula: P = Absolute circumference of a circle "3.14" D = Cylinder or piston diameter L = Piston stroke length Alternatively, you can use the formula 0.785 x Bore x Bore x Stroke. This formula is the same as the one above. 0.785 is the product of 3.14:4 in the formula above. The Jupiter Z piston bore is 58.8 mm. The piston stroke length remains 54 mm, so it can be calculated using the following formula: 0.785 X 58.5 mm X 58.5 mm X 54 mm = 145,069.1775 mm You can divide the above result by 1,000. So, 145,069.1775 mm : 1,000 = 145 cc. Isn't that easy to calculate?
