So I bought a new z125 about a month ago. I love it but it definitely lacks some power for bigger rider like myself. I decided to start modding and try to squeeze every bit of Hp I can get.
Mods are.
Mtake
Musarri full exhaust
EFIE ( cheap fuel controller)
I started with the exhaust and with the baffle out I lost a lot of power obviously. Installed baffle and it ran pretty much like stock. Torque was back and I was achieving the same top speeds. Then I got the mtake and "fuel controller" installed and removed the baffle from exhaust. Adjusted the device and the power is great plenty of torque and faster top speeds.
The EFIE is basically a $30 signal modifier to trick the 02 sensor to read that it needs more fuel. It changes the incoming signal in millivolts so you can "tune" it. So far it's working great. I have a few plugs so I can get everything set up by trial and error. I did get a check engine light for 02 sensor out of range but I think I adjusted it too far. Will post more results after a week or so of riding and resetting the ecu code.
If anyone has any experience with this device please feel free to post your findings as well.
