● 31MM THROTTLE BODY & INJECTOR SET
(FORZA125 (2015-2017) / FORZA125 (2017- ))
● 31MM KEIHIN/YUMINASHI Throttle body set to be installed on the first and second generation FORZA125.
The 31mm throttle body comes complete with the high-flow NLJ-injector (link) to keep the perfect balance between air and fuel without the need for an electronic device.
The stack machined into the throttle body improves the air flow / air velocity which result in a torque and horsepower increase caused by the overal better filling effect of the 4-valve head at any RPM.
We strongly recommend the install of this throttle body set in combination with our GT Gran Turismo variator (link), certainly if your personal body weight is 90Kg (200lbs) or higher to gain top speed.
A 5-pin wire loom comes with the set together with a single throttle cable to make the install on the stainless steel bracket a plug and play experience.
※ Please keep in mind that your air intake hose which connect your air filter box with your throttle body will be too small.
The outer diameter of the stock Forza125 throttle body at the air intake side is 33.10mm (1.30 inches), the 31mm throttle body outer diameter at the air intake side is 47.10mm (1.85 inches).
■ This can be solved with installing the optional Big Tube Air Intake set (link) and to enlarge the diameter of the hole in the stock air filter box.
■ Another possibility is the the install of the K&N R-1100 Air filter (link) which is plug and play on the 31mm throttle body, but will result in more noise while driving.
