I fired up my 01 F4I the other day and it died immediately after firing up, I gave it gas and kept giving it gas so it would keep running. After it had been on a little while it stayed running but the idle fluctuated and the idle kept fluctuating higher the longer the bike was running. I have already replaced all the plugs, and remapped the power commander. Anyone else have any ideas?

 

does it have a o2 sensor? had a car do that once, o2 senser was bad.

 

Whats the range of the idle? Mine levels out at about 1200

 

Did it start to smell of gas also?

 

The idle normally levels at 1400. The fluctuation is about 2000. And no it does not smell of gas, that is why I am leaning towards a bad sensor.

 

Could be a vacuum leak, check your hoses are all connected.
