Vaccum hose leading to the map sensor - cbr 650 fa

[v4fun]

Good evening, David from South of France. i have a cbr 650 fa 2014 which is about 78000km running on ethanol with a kit

The bikes runs on ethanol for over 70000kms. Ethanol or normal gas is the same the bikes doesn t run well
I has never been running well and I have noticed the vaccum hose leaving below the injection to the map sensor was broken in multiples places and not connected to each other.
It has been replaced and connected together. now the bike doesn t accelerate and an engine fault ligh which for once dissappeared came back.
new plugs,
new air filter,
new regulator,
new lambda sensor changed.

Hi David... What is the fault code that's displayed when you trigger it?

Thanks , I don t have a code reader device. Where should it be connected to?

Just the orange engine light on the dashboard

Look at the service manual... There's a procedure in there to display the code. Chapter 4 if I remember correctly.

It only needs a paperclip as a tool (or length of wire).

I think if I connect the brown and green/white stripe from the code error plug I would be able to know what error it is.

Porblem solved for now, i have just touched the TP sensor and the engine light fault disappeared as the engine wasn t accelerating correctly. the bike runs , accelerate (correctly but that s not crazy) rev correctly after 3000rpm , heat correctly
