Is FCE a yamaha term for the ECU? Looks like it, cos its talking of remapping and stuff. A Power Commander might solve the issue though (at a cheaper cost?) assuming Yamaha charges a bomb for such ECU upgrades.
Quality of fuel would play a big part here. First and foremost.


... but just have some technical knowhow, as some of my friends were facing this issue in their older version of FZ1... You can see some forums for more details about this issue and some know how about it..
