good fc.
anyway heres some advise to make ur 4g1 more FC frenly (advise from a otai) :
push the intake rocker arm shafts backward, ikat 22lbs of torque. Adjust the valve tappet to :intake 0.25mm, exhaust 0.35mm.
the intake rocker arm shaft with 4 intake rocker arms. U see, the rocker arm shaft is "adjustable", loose all the 12mm screws, need 2 people to do this:; one guy push backward, while the other guy retorque all 12mm sxrews at 22nm-lbs using torque wrench. Then, the intake valves tappet: 0.25mm, exhaust 0.30mm. easily u can gain 0.5bhp to <1bhp without additional upgrade., its the matter of fine tuning.
set the rpm to 4500rpm, play with the air screw until it really smooth then rev to redline see got kentut or not but before that make sure the step timing is not less than 19, not more than 20.
Make sure the fuel pump is not chap helang or you will suffer fuel starvation at 5th gear@5000rpm. If its g15= 180kmh is nothing. If its 1.3=175 is the max and pls changw its fuel filter every 5k km and always check the ngk plugs from any carbon residue.
Retain original plug cable. You will get 550-600km/full tank on highway provided the exhaust is stock. Better mileage with proper exhaust. Matspeed cam 278 scattered camshaft very cheap. Forget weber or you'll puncture a rather large hole everytime you refuel.
