found the fault today was a roasted wire in the loom sourted it now runs fine but i am goin'g to have to adress heat issue's in the engine bay and wire organasition so i'm going to tidy all wiring up make sure it's took'd safe away to stop any wires gettin melted again and also i think i will cover all wires with heat sheath and thermo tape to stop wires gettin burned as i am plannig a street track slag so the sheath should be a big help under hard use will post some pics when the parts get delivered and i have fitted them
