You will have left the vacuum line to the map sensor off.

The map sensor is a dominant fuel control sensor. With the vacuum line off, it thinks the engine is under heavy load and dumps lots of fuel in, blubbers and runs like sh*t.

If vacuum line is connected and wire connecter in place, it depends if it's high or low, open or shorted, neither of which is common.

Then you probably have low oil pressure. Check your oil level and your oil pressure sender.

hmm.

In that case you will need to take it to a dealership and have it hooked up to find what triggered the FI light.

There are some melting evidence on my dash. They said it could be a bad dash which makes sence.

When it fails to recognise the map sensor it only uses the throttle position sensor and RPM to work out fuelling. The result is an engine that is running rich and doesn't run particularly well at idle especially. It will however keep running.

DO you have a picture of this? That would have to be some serious melting to effect how the bike is running.
