hey guys I know you guys have been messing around with F4is for a while....
I have serched but no success with my problem...

It's a 2002 F4I the bike runs rich big time and is bogging as I ride the bike in all gears, if you hold the gas at a certain postion you feel the power come and go and i get alot of smoke, I guess thats from it running rich...

I tryed switching out computers but it's the same thing..

so if you guys can help that would be coo

thanks for your help

 

anybody?

 

fuel pressure regulator

 

or maybe a vaccum line is off some where...

 

thanks I will check both of those....

 

Yo I'm a new cat... but I was having a similar problem on the same bike... it turned out my battery was low and my ground was loose so the F.I. were not getting enough power *hence boggin out* and also not enough power to sparks so that explained the unburnt fuel... like I said, I'm fairly new so I might be way off... but I figured I would throw it out there. Good luck, hope your back up soon.

peace.

 

yep a low battery could cause the same problem

 

thanks i will check that out too

 

you were right
thanks guys for all your help...
