Honda Grom Engine Swap: Twice the Engine for Twice the Price - CBR 250cc / 300cc How-To

[@christianmcdowell3052]

The diode prevents people from hot-wiring your ignition live. The ECU will only accept the (time to perform) signal when it sees the resistance of that diode. Remember this if you ever replace the keys and locks on bikes.

[@qoph1988]

The diode is also present on older bikes with carburetors and points ignition and no ECU to speak of though. It can usually be removed with some creative wiring if you don't mind not having a clutch interlock for the starter. Sounds like it already served a purpose and then used to serve an additional security function since that's just a good idea when you have an ECU onboard. Otherwise I don't see why they wouldn't just use a resistor

Honda really just needs to keep the grom the exact same profile but fiture out how to make it as fast as possible.

[@ProDigit80]

For fuel Air ratio adjustment, I used a resistor in between the O2 exhaust sensor and the unit. Though the ECU reads the signal digitally, it still enriches the mixture to the point where 1kOhms resistor gets black exhaust soot. But you can feel what setting works best. It's a bit of give and take. Too high of a resistor (I tried with a 1kOhms pot) and the top end suffers, but the bottom will ride great. Too low, and the bottom end suffers. So a mixture (I think I used a 250Ohms resistor, but don't quote me on that).

[@The_Cat_Authority]

Just do it the right way and have the ECU retuned.

Very nice power upgrade. it would be really nice if honda started offering the grom with larger engine size choices. even a 650cc would be really nice. and of course the frame and entire motorcycle would be increased in strength to handle the increased power. i just like the smaller size of the grom, but really need significantly more engine power. 125cc is not even close to enough power for my comfort. i like to be able to move out of the way quickly, as needed, when needed. and overall, i enjoy a more powerful motorcycle, while simultaneously being able to fit the motorcycle well. the grom really is the perfect size motorcycle. it just needs reinforcements where needed, and much much more power, for those of us that prefer more power to be available, at any given time.
