Default f4i idle jumping up (VIDEO)

another f4i problem for me.... doesn't seem like a big one. My bike was idling about 600-650 rpms. so today i decided to make it 1500. i thought i had it set and i bimped the throttle a bit just to make sure and this problem happened. it started idling at 2k and the started going higher eventually hitting 3k when already warmed up in the 170s. also not sure if its just me but does the idle seem inconsistent..?

help if you can

-Ryan



Also two more things

where do these two hoses plug into? the have a vacuum when i put my finger over them

and when the bike is off and i opened the throttle white smoke was coming out of all 4 throttle bodies and smelled of gasoline. (not sure if you can see the smoke in the picture)

check you coolant level. the wax unit brings the idle down as the hot coolant goes through it. if your coolant is low, it will have a high idle. also i maybe hear a vacuum leak. no sure though, hard to tell by the video. look for a leak as well as that can cause a high idle as well.

also i had the tank propped up with the air box off so it was just the throttle bodies that may be what your hearing. thanks again scott

Do you have a manual, page 1-28 should show you where the hoses go.

Hopefully that will show you where they go, I'd get them hooked up and the bike back together then try adjusting the idle again.

It's not really a hose diagram, just a drawing of the bike essentially like yours is w/ the gas tank and air box removed. It shows several hoses and where they go along w/ some wiring. It's in secion 1 page 28.
