Her formula: rear gear Eyes: eyes front gear = Final gear ratio (secondary reduction)
Usually the manufacturer has been researched for a long time to find the right combination for the entire field, both bumpy roads and climbs. Maximum limit replacement final gear ratio is only 0.1! Either shrink or enlarge the amount of overdrive. If too far then do not be surprised your motor shook.
How to find the right ratio must calculate the first plant as a reference standard. Use the smart machine (calculator) so that the calculation becomes faster. Below will be my example right of Jupiter in 2001.
38/15 = 2533 (std), then the max limit is 2433-2633
The greater the ratio the stronger acceleration when it came out in the beginning. Conversely, the smaller the ratio, the breath appears longer and the top speed will increase (CDI unlimiliter, engine upgrades, etc..).
The options are
36/14 = 2,571
37/14 = 2.64
37/15 = 2,466
39/15 = 2.6
39/16 = 2,437
40/16 = 2.5
41/16 = 2,562
42/16 = 2.625
42/17 = 2.47
43/17 = 2,529
44/17 = 2.588
44/18 = 2,444
For the initial acceleration is fierce recommended 37/14, while the top speed on a lap top and a long sigh recommended 39/16.
Not only ratio that affects performance. Large or small size of the gear sprocket or any major effect on high speed. chain as a successor movement to the front sprocket rear sprocket is very efficient at low speeds. Approximately 98%. But, as the speed increases up to top speed, efficiency up to 85% drop chain .Better use of odd and even gears eyed, rather than even-even or odd-odd. In order for the use of gear evenly between the eyes.
Small gear lightly. But, no problem too small. Especially the front gear. Therefore, dental chain that serves very little hook. As a result the work is too heavy gear and friction connection between big chains, wasteful of gasoline.
Gir with eyes too much too have their advantages and disadvantages. The drawback obviously heavier weights. However, the effects of friction during bending the chain in less gear. The movement of the chain on the gear so much smoother. We feel the motor running more smoothly.
