XVS 650 Self Diagnosis problem

Hi there.

I've got problems with my Dragstar Classic 650.

I test drove it before i bought it, no problems, sweet as can be.

Came home, changed the straight pipes exhaust to the original for the SBP (Swedish Car and Motorbike Anuall Checkup)

Started her upp and the Engine Check light started lighting up (as it always does when you turn the ignition)

But when i startet the bike, it startet blinking with intervals, 4 blinks, then nothing for 3 seconds, then 4 blinks again and so on, and so on.

Checked the Workshop manual, which explains that this is part of the "Self Diagnosis"

And that the number of blinks is a code for something, but the Workshop manual doesn't say WHAT the Code Means!!!!

Does anybody know?

I hope that someone has the knowledge so that i can fix the problem.

Could it be that the Bike "feels" that i have changed exhaust system, and that it is warning med for that?

I will only have the original exhaust on for the Anuall Checkup.
