hey guys im just curious what is causing this...
i have a 4age smallport running with a 86kw computer, dizzy, injectors and everytime i give it a hit it blows a shit load of black smoke which = petrol and sometimes through 1500 - 3500rpm..
it also used to do it with my old 4age bigport 86kw runnin 86kw computer, dizzy, injectors... could it be my exhuast system???
