Description

Stock filters get dirty fast and choke your engine. A quality reusable filter + proper jetting makes your bike feel alive again. This is the definitive upgrade for owners who want to “fit and forget.” By moving to a reusable EU-made element and stainless hardware, you save money in the long run and protect your carbs from the common “stripped screw” nightmare.

💎 Performance Upgrades & Aesthetic Value

Why settle for cheap paper? This kit is a long-term investment in your 650’s life on the road.

The Screws: Use a JIS screwdriver for the old screws. Once out, throw them away and use our Stainless Hex-Head replacements!
