Fuel injection light on after air box mod

[GrandpaBusa]

My father recently performed the air box mod on his 2002 busa. He removed the "flapper" in the air box, blocked off the vacuum lines, blocked of the pair valve hose and now the FI light comes on when the bike is started.

Did he do this mod to stop the bike from backfiring? He may have blocked the wrong hose.

No, he did it just to increase air flow in hopes of gaining a few HP

make sure the vacume selinoid (mitsubishi part) is connected...i did the mod recently..i removed all the vacume hoses...remove all the coloured hoses in the dia gram..Except the purple wire connector...AND you can take the short (pink) hose seal it off at one end with a roughthread screw and put it in the left first throttle body ...(where the green vacume hose was connected)....that should do the job..
