    Predator build

    The vibration is more than likely the cause .. The rod is more than likely seized to the crank . No big deal just replace rod an polish the crank

    Filing +.005 rings to fit stock bore

    Alot of two ring pistons use wider expander rings with much larger oil drain back holes . So my guess would be a 3 ring piston only using 2 rings would smoke really bad because of the oil being trapped and not draining back

    What can be done to a true box stock to improve power

    Most of the tracks here in the south have a 5500 rpm limit .and must look stock with all the stock parts an pieces on them .. that’s all they do is look at the engine sitting on the kart and check the rpms .. PS don’t bring a knife to a gun fight .. it won’t be fun
