Reply To: Is it possible to convert GV250 carb model (2007) to run an electric fuel pump?
Fake Emissions Device.
Very very useless on carb bikes.
Korea puts EGR (infamous name) but correct word is “AIS” / 2nd Air Valve to make bike emissions less in stricter EU countries
Here in UK we don’t care , we don’t get checked for emissions on carb bikes, so it is legal for us to remove it for now, thats why we sell the blanks

Bike is happier = why? More vacuum energy is going to the fuel pump now , instead of sharing vacuum energy to pump , tap , and AIS(EGR) device.
The bike will make less pop sounds too. Exhaust may sound a tiny bit better.
1999-2002 GV engines did not have it.
If you remove it, make sure to blank the ports , like below

Ignore the bike is a GT above ^ , the instructions also help GV bikes , they have the same engines and carbs (125cc GT/GV included)
