i have recently made some modifications to my cbr f4i including wrapping my headers and modifying my two brothers exhaust by chopping it down {about half the length of standard} and i have heard both ways about how i will have no power unless i command the bike, then i have heard the bike will adjust itself? Commanding the bike sounds like the way to go but there so damn expensive?

 

COMMAND THOSE HEATHEN LEAN FUELS OUT! DEMAND THAT THEY VACATE YOUR BIKE, FOR THE LORD JESUS CHRIST IS GOOD, AND HE SHALL OVERCOME THOSE DEMONS! COMMAND IT, I TELL YOU!

 

thanks, more thoughts would be appricated-

 

Let me translate...you are probably running lean. Go get a PC and get a custom map if you can. Is it expensive? Yes. Is it worth it? Who knows.

 

anybody else??????

 

wow 2 replys-?-

 

power commmander will help give a pony or two.But the smoothness is where the pc mainly pays off.

 

optimally, pc and dyno tune...

you can run what you got...but if you want to optimze, pc it.

you didn't get so many replies because you didn't search.

 

PC i got mine for 200 bucks brand new on this site!

 

Dew IT!!!!

Dewin it country cool, mountain dew.... (sorry, just had to)

It will get the air fuel running good and keep you from burning up plugs and keep the motor running like it should. I paid $150 used, and it works as good as new....I have seen custom dyno tunes pull 5-6 horsepower on a 600....
