    INFO: Changing sprocket combination and Speedometer reading
    Sniper 150mxi stock Sprocket Combination 42/14

    example:
    14-42 = 3 ratio (stock final drive)
    14-44 = 3.142 ratio (aftermarket final drive)

    3/3.142 = .955 (percent of SFD as compared to AFD)

    So, at any given time, 95.5% of what your speedo says is the actual speed you are doing "Stock Digital Speedo" and Not "GPS"......


    sprocket combination - 14-42 to 14-44
    14-42 = 3 ratio
    14-44 = 3.142 ratio
    3/3.142 = .955

    Let say Based on 130KPH "Digital Speedo" Reading

    130*.955 = 124.15kph
    actual speed - 124.15kph


    130kph "Digital Speedo" Reading of Sniper 150 with sprocket combination 14-44 = 3.142 ratio
    124.15kph "Digital Speedo" Reading of Sniper 150 with stock sprocket

    ===================
    14-42 to 15-42
    3/2.8= 1.071

    130kph* 1.071 = 139.23kph

    ===================
    14-42 tp 15-47
    3/3.133 = .957
    130kph* .957 = 124.41kph

    since Speedometerhealer device is not yet available in our country we can just use this formula at least we know what's the actual speed after changing sprocket combination.

    not really convince if ECU and Clutch spring lang pinalit.. if talagang ng 150kph sya my ibang mods na ginawa.. napaka low compression ng sniper mxi 150 para mg 150kph sa ganyang modification. IMO lng.
