I have a 2003 F4i; When i roll idle at 12, then i bring it down and try again to bring it up at 12.. the bike bogs down and doesn't want to go back up.

I read the forum for a solution and tried the AirMod; So i went out and practiced today and same **** happened again.

any idea whats going on?

 

yea sell it and buy a 636 its normal...

 

as a matter of a fact i have an 03 636 for sale...

 

LoL!! i refuse.. to go over to the dark side.. i'll stick with the F4i for now.

 

make sure you dont have any vaccum lies off or leaking. one of mine came off and it ran like that, fixed it and now it pulls like a champ. and shane, ur an *** for moving to st luie

 

i did notice i had one of those small little tubes disconnected. but i don't think that would make a difference. :/

 

find where it goes and fix it, I bet the bog gets better. its a F4i, it will never go away but it does get better.

 

i double checked all the hoses on the bike double tighted them up with zip ties.. .. i rode all day yesterday and it was perfect!

thanks!

 

I never got an email from you homey and just found this thread on stuntlife...F4i's have crazy bogging issues when the vacuum lines are not on/on tight. Glad its running good for you now

 

its cool :D

i took pictures but couldn't find the cord for the camera.

 

try syncing throttle bodies also if u have a ecu u could swap out and try it some ecu have that prob also....

 

he fixed it...

 

i had the same prob i had my tank off and got in a hurry before yo face! and i ended up wrenching on my bike for an hour instead of riding....
