● 35MM THROTTLE BODY SET (IMPROVED FORZA300 THROTTLE BODY) (+164CC KITS)
The main reason for the Yuminashi R&D to start with an improvement on this 35mm FORZA300 throttle body, and also on the Yuminashi 31mm throttle body actually, was to solve the issue of tending to run very rich while running lower RPM's on a stock ECU, and this with about any injector type, where it was very hard to pick up the RPM's then if you suddenly open full throttle. The formal generation 35mm throttle body tended also then to run quiet lean in the higher RPM region where we want to see the opposite actually with a well balanced air fuel ratio engine...
The improved stack design in the throttle body, in combination with the improved Manifold Absolute Pressure sensor/Throttle Position sensor and Air Intake Temperature sensor block makes sure that you get a serious improved and much better balanced system right away... The 5-pin connector on the large sensor block isn't located anymore on top of the throttle body, but below on the side from the throttle body.
The set comes complete as shown on the pictures.
For racing applications best performance will be achieved without air filter.
For road use we recommend to modify the stock air filter box, and if you have a PCX125/150 or SH125/150 then you can use the Yuminashi Big Tube Air Intake set, or an original air filter K&N R-1100.
If you have a A-type manifold like the AIR BLADE i or CLICK110i then we recommend to install the A-type 6 holes high performance injector.
If you would like to install the 35mm throttle body (with 5-pin connector) on a MSX125/GROM125, Zoomer-X, Vision 110, Click125i, etc then you will need to use the correct wire loom (5-pin to 3-pin) to make the connection possible with your stock wire harness.
※ For MSX125/GROM125 a plug and play 35mm throttle body set with wire loom is also available with part number 16400-K26-034US, and need to be installed with manifold set 17110-K26-35FB (LINK).
