    Jetting a GSX 400 (8V) for unifilters,stock headers and shorty mufflers

    So i'm about to start first time, BS34ss carbs were rebuilt with new o-rings and gaskets.
    Bike is the euro version
    according to the manual main jets are 117.5
    pilots are 42.5
    needle is 5D69 (it got slots)

    My setup is uni filters,stock manifolds including the link pipe and short slash cut mufflers.

    do i need to change the main and pilot jets?
    would going to 130 mains might be correct? how much should i step up the pilots?

    Thanks
    Eran
