How to get a spark arrestor KLX140 FMF Slip on

Recommended Posts

Just bought my kids a 2017 KLX140 and we want to take it out to the trails.  The bike has a slip on FMF pipe without a spark arrestor....any ideas on how to get one?  I cant seem to find an arrestor online that I can slip in.

FMF makes spark arrestor inserts for most of their models. The US Forest Service is super picky especially depending on the ranger. The FMF inserts are forest service approved, it just wont be stamped on the outside of the silencer. I set my coworker up with one of these for his RMZ400 Titanium with the quiet core and sparky, much more camper friendly in the woods and no loss of power. Go to the FMF website and have your model of silencer and bike,

The Mini PowerCore4 for the KLX140 can be purchased as an entire unit with or without the Spark Arrestor Insert. I would contact FMF directly and ask their customer service for more guidance.  If they sell the Spark Arrestor with the Mini PowerCore4 they should have a replacement part to accommodate your situation.  The replacement parts page on the FMF site lists several replacement spark arrestor inserts for the PowerCore4 (not specific to the Mini PowerCore4).  They should have it and it will likely be comparable in price (+/- $29.99).
