I know right! Not a great way to start but hey nothing I can do now.

They did dry everything out initially. Seems as though the Yamaha guys figured it out. Turns out the injector was faulty, it wasn't closing properly so just kept injecting fuel. They swapped injectors with another XT660z to test and all came right. Ran diagnostics again and all sorted.

Good to know it wasn't anything more serious.

Here's to many happy km's on the bike!

Cheers!
