problem with Pro Circuit TI-6 spark arrestor

[MXer83]

Hello,

I bought a new TI-6 system for my KX250F. But there is a big problem with the spark arrestor. I've already tried everything, but it is not removable. It stuck! Is there a trick?

Thanks.

What is stuck? Exactly where?

The arrestor could not be extended and can be pushed just a little inside...
