Re: f4i boggin like crazy! HELP!
ok so i just got the new motor in and going.... new plugs, fresh oil and oil filter, new k&n air filter
when i crank it up it has a weak idle, it boggs REALLY bad and when you blip the throttle it almost dies .... but if you can get it to rev past 6-7k rpms it revs and sounds fine.... checked ALL hoses and whatnot.... any ideas?
no smoke.... it runs basically like a bike would if you just took off on a cold day w/o lettin it warm up.... only worse caus a cold motor will still rev.... i dont know what else to try, no FI light or anything, just runs like ***!

My F4i has a bit of an idle problem when I first start it up. It usually won't turn up until the bike gets warmed up...BUT even after it warms up, I have to shut it off and re-start it and then I can get the idle up to 3500-4K. It's weird but it's what I have to do.

If not thats probably your problem.. The stock idle dosn'et actually open the throttle

Re: f4i boggin like crazy! HELP!
if your missing the second idle then your butter fly's dont have the stock set screw in, them so thats why when your second cable came out it started to run weird ..when you put the second one in did you notice that you had to remove a set screw that is pre set from factory.so with nothin there the butterfly's are almost completley shut making the engine idle on the air idle control valve alone

so much knowledge here!
well XDl is comming up and i took my powerless (not bogging) motor out of my 2001 f4i
and put my powerful snappy 2002 f4i motor in the 01 frame.
well when i ride now the bike has power spurts then dangerous boggging issues, (very twitchy)
funny thing is, that powerless 01 motor is running strong in my 02 f4i?????!
so now i need to figure what is up is it
vaccum?
electrical?
fuel?
bad (old) part^
I am going to sync the TB's
then imma check all conections
then imma even try a stock airflter...
any other ideas?
my bike has a stock header with A 9 INCH YOSH CAN
k&n filter
60 rear sprocket 15 front
i need to get this straight i havent rode my bike for close to a month now!!!
but i did go ride the bike once to ffind that my bike is running crappy!
my combos got crappy do to power loss!!!!!
my stalls got better cause i have to stay on the clutch to save my as*
i have a mechaninc helping me through this but he doesent seem to know f4i's
so any mech. lingo i can send to him will be great,
