    hi my bikes got the following parts

    Malossi MHR reed block
    PM Tuning 360 exhaust
    Polini Variator
    Malossi MHR 70 kit – ported
    Malossi 5.5g roller
    Malossi torque spring
    21mm Malossi carb 86 jet
    straight inlet manifold
    Polini evolution crank
    Srt lightend fly wheel
    polini evo 2G clutch


    and every time i full wak off the line the bike bogs, and when it does get going theres no power bound jus lots of revs, i tried heavyer rollers and it jus make the bike slower. even when i kick it over theres not that much compression. the bike performes better at quater throtle for some strang reason

    WHAT CAN I DO TO MAKE IT RAPID AGAIN HELP PLEASE LOL . :beg:

    lack of compression and lack of power sounds like theres something a miss with your top end...

    could be your piston ring gone!!
