● NEW 2018 YUMINASHI /KEIHIN 31MM THROTTLE BODY SET FOR HONDA LEAD125 & AIR BLADE (2015-2016)!
Because the best is only good enough!
With the new 2018 model 31mm throttle body for 2015-2016 Honda AIR BLADE 125i the YUMINASHI R&D worked a TOTAL SOLUTION out that covers all issues with upgrading from the stock throttle body in to a larger version which is usually in combination with a big bore kit.
The first very noticeable difference compared to the formal model is that the IACV valve is gone, and has been replaced by an air adjust screw in the same fashion as you can find them in a carburetor. Like this it's really easy to get your idle mixture right and with this you actually hit two birds with one stone since this is also the solution for a sometimes hard to start engine like a AIR BLADE 125i with a 164cc or 175cc kit installed.
If your electric starter have a hard time to make your engine turn, then adjust the air screw on the new 2018 throttle body, give it some adjustments with turning the air screw to the right, and you will see that your electric starter have no problem what so every anymore to turn your crankshaft around and to start your engine.
The new stainless steel bracket/throttle cable holder (which can be ordered as a separated part over here), is installed on the new 2018 throttle body to make your install as easy as possible.
The 31mm throttle body comes with the SPECIAL YUMINASHI SENSOR BLOCK INSTALLED to allow easy AFR tuning/rpm pickup when cruising around and whacking the throttle open without any hiccups, the torque will be right there!
A stock CBR150R throttle body can be used as an alternative, and many vendors are selling these all over the world, but it’s really hard to get your tune right, certainly with the stock ECU installed.
With the Yuminashi 31mm throttle body, the stock AIR BLADE 125i ECU can be used because of the specific special installed Yuminashi sensor block!
The main reason for the Yuminashi R&D to start with an improvement on the 35mm, and also on this Yuminashi 31mm throttle body, 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.
It was very hard then to pick up the RPM's if you suddenly open full throttle. The formal generation 35mm throttle body was also tended 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, so the use of the newly developed sensor block is utmost recommended!...
The 3 connector wire loom which comes with the set makes it really easy to connect the throttle body to your stock wire harness.
The 5 pin connector connects on the large TP sensor on the throttle body, the 3 pin connector connects to your wire harness, and the 2 pin connector connects to your AIR BLADE 125i Intake Air Temperature sensor.
** This throttle body need to be installed with the B-type manifold set 17111-KZR-000SC which you can explore over here.
*** For best performance we recommend to install the 17253-KWN-000 Big Tube Air Instake Set to be installed on the stock airbox (Click here)
(airbox diameter need to be modified).
