Need some help. I have an F4i that sometimes won't hold idle. First couple of sessions of the day it runs fine and pulls good on idle, it will also keep a consistent idle. After the third or fourth session the idle starts getting sporatic, if I put it at 3000 rpm it will drop to 1500 to 2000 after each wheelie and I have to adjust it again. Small increments of adjustments on the idle will make it jump from 2k to 3k which is annoying because I like it at 2500 for circles.

It only allows me to be at either 2000 rpm or 3000+, no where in between. The thing that is the most confusing is that it will ride perfect for the first hour I'm riding in then it will run like ****. It will literally pull like a tractor then later on I will have almost no idle to work with. I pretty much can't turn circles after it falls off...

Here are some notes and things I have ruled out...

The temperature stays consistent at about 180-190

Changed the plugs this morning and nothing changed

I am using a second idle adjustment on the front of the throttle bodies

I recently switched the tank and fuel pump

Its like the choke gets turned on?

 

clean your airfilter maybe...that wouldnt really cause the bike to do it after an hour though....but try it anyway

 

Im thinkin its any one of your sensors already burnt up. Gotta test em all.
