Hello,
Had someone disassembled the end of the exhaust?
In the service manual looks like it is possible, but when I disassembly end cup of the exhaust there is one more steel cover which is welded.

Hey @Jan: I thought the same thing over the past summer. I doubt I will ever clean my spark arrester. I've never cleaned a spark arrester in four decades of riding, that is, it has never been an issue or hazzard.

By the way, welcome to the Forum!

What does your ride look like @Jan?

Possibly new in 2021. I cleaned the arrestors as part of one of the services and they were accessible.

I lied.

I cleaned out my spark arresters on my '76 Yamaha RD400. Half of the effort was removing the rust dust, and then whatever was left of the arresters.

2020. I guess Europe doesn't have any more forests to burn down, so no need for a spark arrestor.

Our Green EU maffia buying woodchips from south America to burn here for electric to feed EV. It is a big crime if we remove the spark arrestors therefore they welded to the exhaust EU regulation.

Doesn't look like there is a factory spark arrestor at all. This is looking down the large pipe.
you see the exhaust servo valve at the end (out of focus)
