    Default Increase the speed of Honda Deluxe 125 (5G Spirit)

    Please suggest something to increase the top speed of Deluxe 125, currently it goes maximum up to 110KMPH. I just want it should reached upto 120KMPH.
    I installed Iridium Spark Plug, uses fuel additives (octane boster / fuel system cleaner etc) but these only help to make the ride missing free.
    By default it has 14 x 43 sprockets, I installed 15 x 38 sprockets but it was totally bad experience. Bike's pick up was fu*ked and was going at 110KMPH in 4th gear then 5th gear was reducing the speed rather than increase. So I changed 38 sprocket to its default which is 43. Now sprockets are 15 x 43, but still it barely reaches 110KMPH as it was earlier.
    I would like to request you to please suggest something which can increase its little accelaration and its top speed up to 120 - 125KMPH. BUT IT SHOULD NOT HARMFUL FOR THE ENGINE OR BIKE AS I DO LONG TOURS AS WELL.

    Your opinions will be valuable for me
    Thanks

    its not about dirt - the air filter provides a certain "blockage" for the carburettor to work properly. We know that air is lighter than petrol and when you allow free flow of air into the engine petrol wont like to be sucked up from the carburettor - (basic carby tuning)

    Furthermore if you were doing the "pilugg ka colour" tuning and were allowing the engine to idle down before you shut it off then nothing could be seen what was happening.

    That is why plug colour technique of jetting is done at various throttle ranges.

    I don't know about plug colouring. All i know is that one foam worked just fine for me. Although i put it back on because it was way too much. Still altering any thing out of the ordinary has its own dis advantages

    replace your clutch with new AHL orignal clutch box ,cultch plates & pressure plates

    (if too old) to improve your power & rpm @8500

    than you easily achive 120- 125 kmh
