    jetting issues

    Post by Mills on Thu Jan 03, 2013 6:06 am

    hey,
    just been out on my pk 50 and its had no guts and struggled to get over 20 on a flat. it then broke down on me and wouldn't start back up.
    Ive been told that its pumping in too much fuel. it currently has a polini 50cc kit and a sito plus exhaust, anyone got any ideas what size jet i need?? the main jet in there at the moment is a 55
    thanks
    Matt

    How did the engine behave before this happened ?
    Have you recently added the polini 50 kit ?

    It was bogging down loads and struggled to get any speed up, then it was loosing revs and just died completely and it you could smell fuel. And a mechanic that had it last time put it on.
