● YUMINASHI 155CC/MIN B-TYPE (12-HOLES) FUEL INJECTOR
● This 155cc/min B-type 12 holes injector from the Yuminashi Racing Department has a 15cc/min higher flow rate compared to the very popular PCX150 injector...
With the 12 holes instead of the stock 6 holes the atomisation is improved which make a much better air/fuel mixture possible with improved throttle response and top speed characteristics.
The 155cc injector is recommend to be used on a 2-valve engine starting from 135cc until 165cc, where a 135cc engine will have more torque compared to stock because of the richer running engine, and where a 165cc engine will have less torque, but a better fuel economy because of the leaner setup.
If you would like to give your stock 2-valve 150cc engine more torque, then we recommend to install a 170cc injector.
※ Keep in mind that the MSX125/GROM125 - WAVE125i / INNOVA125i - Z125 MONKEY - SUPER CUB C125 have one of the smallest valves installed from all engines/bikes listed below with as stock/standard a 90cc injector which you normally can find in a stock Honda 110cc engines.
If you have one of these bikes, then you could go for the middle way with installing the 120CC F-injector (LINK) in combination with the stock camshaft, as a good way to avoid a too rich running combination...
※ If your stock injector is 140cc/min such as the PCX150 (please scroll down how to read your injector below), and if you want to change your fuel to E85, then we recommend to install a 180cc/min injector to have a good fuel economy and a 210cc/min injector to have some more torque in combination with E85.
Rule of thumb here is the injector flow rate/min you have selected to run with normal fuel times 1.3 to get the flow rate/min with E85.

● INJECTOR READING:
How to know which injector you have, and which one should be the right one to replace it to have the same fuel rate, or a higher fuel rate then you already have installed?
With the guide below you can see based on the injector "name" which injector you have installed on your bike, and which one you should take to make your bike run richer or leaner.
Keep in mind that you first need to know if you have an A-Type injector, or a B-Type injector.
With the A-Type injector, the letter on top of the injector tells you the "name" of the injector.
With the B-Type injector it is actually the opposite, because the letter, or letters below, are telling you the "name" of the injector.
How to recognize an A-Type and B-Type injector?
Well, it's actually easy to see because the A-type injector is perfectly round and smooth, while the B-Type injector have these Pins left and right that protrude, it not perfectly round and smooth at all.
※ If you have the large throttle body model, with the large square sensor block, then you can install both injector types on your throttle body, you only need to buy the correct injector joint, and possibly the correct wire loom if the A-Type or B-Type injector wouldn't be the stock injector type of your bike...
