Stock bike except for the front air flap removed. Its the only error we read on the computer. Bike revs fine till 7000 rpm and then the AFR goes to 10.0 and thats all it does. Any ideas?

600 Km on the odo
Stock exhaust will all catalitic converters, lambda, etc
Stock ECU with stock bin file

AFR 10 is over fuel...

Thanx for the reply.

Believe the bike was bought by someone to use as a race bike and he did not like it, so he sold it.

I guess I will have to start stripping and check. Would like to know what you guys will check for.

Was thinking:

Blocked intake
Blocked exhaust (valve / Catalitic converter)
Confirm the bin file is stock
Air filter
Stuck exhaust servo

Anything else to add?

Will give you guys some feedback yea. Maybe a photo of the rat as well

So it came down to the previous owner mounting the exhaust servo wrong. It did not open. They had an aftermarket exhaust on the bike and before selling it, they put the stock one back.
