2020 xtrainer spark arrestor

what are my options for a spark arrestor?
whats everybody running?
is my only choice fmf?


1st thing i need is spark arrestor, 2nd would be the more quiet the better.

any comments would be great

ProCircuit also makes a SA for your bike. But FMF will be quieter.

picked up the fmf turbinecore 2. easy install. no difference in tone/noise. no power difference that i can tell.

Fisch Moto makes a slip in. Ordered two last week. I’ll update on fitment when they arrive.

stoneywv,

****UPDATE****
So I got the FISCH spark arrestors in and was little concerned with the reduction in inside diameter for the size that fit the 2 Stroke exhaust pipe. Well I took the time to install the larger one in my 200rr and installation was super simple. Packaging was great with Allen key and lock-tite supplied. Took it out for a ride and the entire ride I was feeling like the bike was just a little flat. Got out on in the grass field and rapped out the gears and it was falling on it's face in 5/6 gear at 1/4 throttle and then cracking wide open.
I thought maybe it was the temp increase over the last few weeks that got me in trouble with jetting. Then I remembered I had installed this arrestor and proceeded to remove it and go back out for another test. Well front wheel was coming up in every gear through 5th.
Consensus is this restricts the tuned flow of the exhaust too much to run it in a 2 Stroke bike with factory exhaust. Pretty unfortunate as it would have been a great alternative to the $225 FMF slip on. Now I have a $75 paper weight to hold the receipt down from my FMF when I'm unboxing and installing it. EPIC FAIL

stoney,

wow. i wonder if it would work on a 4 stroke machine.

I would say yes, I've used the small and large tip on my aftermarket spark arrestor on my YZ250FX and it doesn't make a difference on power that's noticeable just quieter.

Gentleman, a screen type SA never works on a 2t. The oil in a 2t clogs up the screen in short time. You can run them in a pinch but they are a constant miant. problem. That's why all of the commonly used SA's are built with the turbine type.

For a 4t. the will work for ever! A few months ago, I lost my SA from my FMF SA in a sand wash. I got on of the FISH brand and installed it. No problems.
