Hello all,

I have just installed an Arrow Rebel homologated exhaust system on my Vulcan. I made few rides and now I see Engine warning indicator. In owner manual is written only this:
"The DFI system has malfunctioned. Have it checked by an authorized Kawasaki dealer."

Do you have any experience with it? Dealer of exhaust system wrote me that any changes in motorbike unit is not needed.

Thanks! Petra

Most common cause after changing exhaust is an O2 sensor fault, typically because it was not plugged back in properly - double check the cable routing making sure nothing was damaged and make sure it is plugged in properly

Hi, during my way back home indicator alone turned off, before I was able to check O2 sensor. During another trip no problem occur. Maybe it needs somehow sit down all parts together or something like this. Engine working well.
So thanks and good day!🏍
