original engine ,removed the restrictor from the air filter box
build in the yuminahi power commander and plugged into the laptop

than changed the parameters and still working on them
standard run on the meter showed me 120km/h
after the modifiing 140/150km/h (on the meter ,these are not street speeds )

now we gonna change the sproket in front 15 to 14 and yuminashi race cam also we need to change the valve springs into stronger ones

I wish I could adjust it like that on the API but sadly you cant

 

[fred]

wel the api seems like just the same but like you mentioned it can't be adjust
therefore the yuminashi is better

Wow, your fuel curve looks way different than mine, but I'm shooting for 13.2:1. I have the 150cc kit on, 31mm throttle body and yumi cam. What was the ambient temp that day? What A/F meter are you using? I am using the NGK and ill be on the dyno this saturday to tweak it.

Are you still using a cbr125 tb? Is there a MAP sensor build in?

 

[fred]

cbr125tb?? yes there is a map build in

 

[Snakeibf]

The cbr 125 has a MAP sensor but it isn't located on the throttle body. The sensors on the TB are a IAT/TPS which is a combined unit and it has a IAC. I have a pretty thorough breakdown and comparison on my website and I even show which wire colors to connect from the MSX to the CBR throttle body to make it work. Right now I have a cbr 150TB installed.
