Hey, my f4i was full fairing until today, I took the intake boot things that go to the airbox and now the bike is far louder as far as intake noise butttt... now there is like a bog down low in the revs (right off stock idle set at 1k) as well as some power missing down there. Is this normal? What do you street fighter guys do?

The bike bone stock engine wise (even intake filter) except for an old power commander.

 

take the power commander off, they're junk.

 

thats normal,you'll get used to it

 

intake boots are for the garbage

 

why put a power commander on a bone stock bike?

 

Ive heard and seen that some people tape up one side or both sides of the holes on the airbox My boy taped one side and said it helped the power down low

 

if you remove the intake tubes u need to tape up one side of the airbox. my bike came with a k/n air cleaner and had no bottom end and a huge bog till i taped up one side. also make sure you run a stock air filter that will make it bog as well

 

Tape one side of the air box up or put the boots back on...

 

Came with it.

Thanks guys, I'll tape up one side and roll with it

 

yes sir!

 

or you can just crunch up a small to med. sized paper bag and shove it inside one side of your airbox and see if that helps. worked for me

 

Sick, ductaped one side up and it is about back to normal
