Hello, help with broken Lamda

Hello

Just purchased a 2013 M800, love the look and forward controls, the ride is amazing.

Hope to get some help and advice to improve the sound of those factory pipes, also I've got an issue with the lambda sensor which I'll explain below, hopefully someone can put my troubled mind at ease!

Here goes, when I purchased a couple of weeks ago, the guy in the bike shop told me to remove the Lambda sensors can cap them off!

Well, this afternoon I tried to remove the rear Lambda and it snapped!

Now I have a hole in my exhaust and the F1 red light is on.......

I have about 2 threads on the screw part, I guess the rest is still in the exhaust.

Any suggestions on how to get the remaining part of the Lambda out and turn off the F1 red light?

Also would it cause any further damage if I ride as is until I can get it fixed!

Hope to hear from some experienced owners out there before I try to fix and probably hash it up even more.

Finally do Intruder owners meet up, if so I'd love to know when and where, would be great to see some other examples of these machines.

Many thanks

Hi Jason .. found this on the US site.    I don't know if it will help.
