FISCH MOTO Spark Arrestor Kit 35 — 35.5–40.4mm Stainless Steel, USFS‑Approved, Installs in 5–10 min

The Fisch Moto Kit 35 is a USFS-approved stainless-steel spark arrestor that fits 35.5–40.4mm tailpipes and installs in minutes to reduce ember discharge from off-road exhausts.

This compact, Canadian-made spark arrestor from Fisch Moto is designed for dirt bikes, ATVs and other off-road machines with round tailpipe outlets between 19mm and 56mm; Kit 35 covers the 35.5–40.4mm (1.398"–1.591") range. The arrestor ships with mounting hardware, an Allen key and threadlocker so you can secure it quickly and remove it just as easily for cleaning. It meets USFS guidelines and is available in multiple sizes so you can pick the correct unit after measuring your exhaust outlet.

How quickly can I install the Fisch Moto Kit 35 on my bike?

Installation is designed to be straightforward and done with basic hand tools. Most riders report a 5–10 minute fitment time when the exhaust outlet is prepped and any obstructing ridge is smoothed away.

• Includes set screws, Allen key and threadlocker for one-step mounting
• No welding required — clamps or screws secure the unit
• Prepare exhaust by removing burrs or ridges for a snug seal
• Quick removal for cleaning or inspection

Will this arrestor fit my motorcycle or ATV?

Measure the inside diameter of your exhaust outlet to determine fit: Kit 35 covers 35.5–40.4mm. Fisch Moto offers eight sizes in total, so you can choose the one that most closely matches your tailpipe diameter for a reliable fit.

• Universal round-tailpipe design accommodates many brands and models
• Compatible with most dirt bikes, ATVs and enduro machines from major makers
• Not suitable if exhaust has an unremoved ridge — grind down ridge before ordering
• Check manufacturer compatibility lists for model-specific exceptions

What maintenance does the spark arrestor need and how often?

The arrestor contains a mesh or baffle that traps hot particles; regular cleaning preserves airflow and prevents clogging. Recommended service intervals differ by engine type and riding conditions, and the arrestor is simple to disassemble for inspection.

• 4-stroke engines: clean every ~100 hours or about every 6 months
• 2-stroke engines: clean every 15–20 operating hours due to higher residue
• Removable design allows easy access for brushing and light solvent cleaning
• Inspect during routine service to avoid performance loss

Is the Fisch Moto arrestor durable enough for off-road use?

Yes — the Kit 35 is fabricated from stainless steel to resist rust and withstand rugged environments. Its build quality is intended for repeated removal and reinstallation during routine cleaning without degrading the fitment or function.

• Stainless construction minimizes corrosion on wet or muddy rides
• Hardware and threadlocker included for a secure, vibration-resistant install
• Canadian manufacturing with attention to fit and finish
• Designed to retain structural integrity under typical off-road loads
