    XPL jetting help - big bore and coffmans

    Hi all


    I am about to put together my big bore (1050) with my coffmans. I have a advent t4 ignition which i am installing this week. The engine runs ada billet head with 165psi and carbon reeds and 13/19 dynafly.

    I was thinking of removing the accellerator pump and running 125 lows and 165 highs... do you think this will be enough.. I really want to keep the stock carbs because i love going wave jumping with the boys, but also plan to race with the local club...

    Any help would be appreciated...
