First off i have a 2001 f4i

I went out and started the bike to let it warm up and it sounded fine. Then i came back outside to get on it and it was idling under 1K RPMs and it was not a consistent idle either. Along with that the FI light would blink twice and then pause and blink twice again.

I did not have time to look at it for about a week because of school and then i went out to look at it again i started it up. Let it warm up. and then after a small adjusment to the idle speed it was idling correctly...1500 RPMs (i had messed with the idle speed the first day) So then i gave a quick roll on the throttle and it reved up just fine but then dropped down to about 500 RPMs and then it would slowly come back up.

I tried riding it just down the street and back and it seems like if im on the throttle it runs normally.

I have no idea whats wrong. Please help!

 

is it cold where you live?

 

make sure this part of your harness is hooked up..dont if that could be the problem, but this almost same thing happened to me and i just forgot to plug this back in...ignore the other little yellow circle around the hole at the bottom.

 

It has been cold lately but i always let my bike warm up before i ride it.

In that picture is that the right side of the bike? (when sitting on it)

 

my bad, yes..it is the right side.

let me know if you need any more pictures.

 

i took off the right fairing but i guess i have to take off the gas tank as well because im not seeing it. is that correct?

 

Yeah, you'll have to prop the gas tank up a bit to see it.

 

just lift it and rest it on something off to the left..(forgot it was this hard to get to) my bike has been bare for the winter..so i didnt have to take anything off to see it.

 

did you get your problem fixed?? if not let us know..im sure there are some other reasons i could come up with if this isnt it.

 

Map Sensor....Check the plug....=-)

Also, IF the bikie sat up for an extended period of time. I would change the oil, drain gas and put new gas in it......Be surprised what can go bad when it sits up...=-)
