Sorry for the late reply here. I have been overseas.

Yes. The bike starts and runs fine with the replaced barrel. It doesn't need the old keys to be anywhere near the bike.

I have the old keys for the fuel cap and the seat lock.


The replacement barrel and keys are genuine Yamaha XT660. Bought from Ebay in Italy !!

The barrel and the key are a match. The barrel won't turn without these keys. The original keys do not work in the ignition barrel.


As far as I am aware, the ECU is the original and the barrel is off ebay !

Should this work ?????
