Cobra silencer on ATC 250R, Spark arrestor?

[crackshot]

Does anyone have one of these silencers?
If not, how can you tell if it has a spark arrestor?
The end is riveted so if I were to repack this, do I have to drill out the rivets?
I cannot find any information on Cobra silencers for ATC 250R's.

I have a Cobra on my Tecate, You have to drill out the rivets to repack it. Yours looks pretty new, so that shouldn't be a problem yet. You would probably have to buy a "Sparky" one of those clamp on arresters.

if you can look through the silencer with no viewing obstruction then it is not spark arrested

So whats a spark arrestor? A piece of stainless screen that covers opening and thats it from what I see.
Nothing that a hose clamp and a slice of screen won't fix!

if it doesnt say s/a on it usually it isnt....a spark arrestor usually is a series of stainless screens in different shapes depending on the brand. it wouldnt be a legal spark arrestor unless it is USFS approved anyways, so if it doesnt say it you have to get a sparky or something like it. there isnt any point of having a spark arrestor unless you need it to ride legally. and there isnt nay point in making your own because ti doesnt count unless its USFS approved....

The forest around here wants yo to have one. I kept my stock silencer if I have to swap real fast!
