hi im newbie driving Viva 850 mild mod.
Love to track at Sepang and join local event time attack.
Spec:
light crank pulley
Adj cam pulley
Hotbits 3-1
KnN open pod
Denso Ir plugs
Oli cooler
full ultra racing bars
passo caliper with AR rotor
Pro Rs hoses
ATR k-sport tyres
So far response is ok but i need a little more for my top end power
i know using light pulley and adv timing will provide good respond
but lack in top end power.
so far on straight line at Sepang i can do 140km/h
Aiming for 160km/h at least
Some mech advised me to change a slightly bigger injector
stock 175cc change to MDH 210cc
Its that method works:hmmmm: coz stock injector cant support when high reving:hmmmm:
If i change the injector. should i change the fuel pump:hmmmm:
I dont mind to change the fuel pump to Walbro since in future i want BOT.
Tq....:proud:
