● GENUINE KEIHIN 120CC/MIN B-TYPE (6-HOLES) A.K.A. "STUNT BIKE" F-INJECTOR
● This injector has the nickname "Stunt Bike Injector" because this injector will give your 110cc bike and even the small valve 125cc MSX/GROM and Z125 Monkey engine a lot more torque, and this makes it perfect as drop-in injector for stunt bike use with good throttle response.
This injector is the recommend injector to be used on the Honda 110cc engines with a 53mm and 54mm big bore kit.
The classic drop-in injector for the MSX/GROM is the PCX 150 injector, which you can find over here, which is actually a Keihin H-injector with a 140cc/min flow rate, and is a perfect injector for wide open throttle at the freeway since it will provide your stock 125cc more fuel in the higher RPM region.
If you are using your GROM/MSX/MONKEY125 as a stunt bike, then you absolutely will love this Keihin F-injector since this circle pattern 6-Holes F-injector with 120cc/min flow is perfectly positioned between the stock 90cc flow rate injector and the 140cc flow rate PCX150 injector, so it will give you right away faster throttle response, faster acceleration and much more punch between 500 and 8,000 RPM's compared to the classic PCX150 injector...
The F-Injector can be installed on any GROM/MSX/MONKEY125 between 125cc and 164cc and this with the stock ECU or a standalone ECU.
■ Keep in mind that this injector will lean out with a 164cc big bore kit and the stock ECU above 8,000RPM so it's perfect for a trick bike and cruising around but not for WOT on the freeway...
The 140cc/min flow rate Keihin H-injector ("PCX150 injector") can be found over here.

● 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...
