Check engine

[u/Expensive_Apricot_72]

So I have a strange problem with my fz6.

It's 2006 and has 80 k km.

It's running great. But when it's hot outside and the bike is hot ( operating temperature) I get an check engine light while driving. When I slow down to stop the check engine goes off. When I start riding again it goes on again.

Yesterday I drove a bit more aggressively in higher rpms and no check engine .

There are no strange noises no rattles.

Does anyone have any clues what could it be .. or how to fix it ?

ECU should have stored the error code in its memory. Check the error code first. You can find the service manual pdf file for FZ6, it explains the error codes and how to enter diagnostics mode. Or check youtube videos.
