Does your Kawasaki KLR650 feel like overheating quickly or backfiring a lot with your aftermarket exhaust? That’s thanks to the stock air injection system—great for emissions, not so great for performance.
 
The PAIR system feeds fresh air into the exhaust to aid in the combustion of unburned fuel. It was designed to improve emissions but will cause problems with many aftermarket exhausts/mufflers.
 
This Air Injection Delete Kit for KLR650 Gen 2/Gen3 (2008-current)  lets you ditch the unnecessary plumbing, reducing popping on deceleration and cleaning up the engine bay for a more streamlined, adventure-ready setup. Built to replace the factory air injection system, this kit includes everything you need to properly block off the ports and get your KLR back to its no-nonsense, rugged roots.
 
No more extra hoses. No more clutter. Just a simpler, smoother-running bike ready to take on whatever the backcountry throws at it.
 
✔ Improves throttle response by eliminating unwanted air injection
✔ Reduces deceleration popping for a cleaner, more controlled ride
✔ Clears out unnecessary components, making future maintenance easier
✔ Durable and precise fit—no weird workarounds or janky DIY fixes
 
Perfect for riders who believe in simplicity, reliability, and keeping things running the way they should. Ready to let your KLR breathe like a real adventure machine?
