[mnfazyze]

My wira converted to 4g93 with 4g94 crankshaft.open mod.
The engine still berpantang.usually drove under 3.5k rpm.when i try pedal to the metal (under 4k rpm) it will jerk.when i drove it normal till 4k rpm, no jerk.
I still havent install management yet.wait till habis pantang.
Anyone can explain to me.is it coz of needed management or sumtin else?

I set my fuel regulator at 1.5
Should i go to 3.5?

 

[mnfazyze]

Maintain 1.5
Upper no good.worse.
Coz i use 450cc injectors. Management is the answer

450 maybe too big la
n need standalone
