Moto-House MX Pro Tip:

Fuel injectors are the lifeblood of electronic fuel injection (EFI) systems, and even microscopic debris can ruin your riding weekend. When an injector clogs, it causes your ATV to run lean, which raises combustion chamber temperatures and can potentially damage your piston. Installation Tip: Before removing your old injector, thoroughly clean the entire surrounding area on the throttle body to prevent dirt from dropping into the open port. Lubricate the new injector O-rings with a tiny drop of clean engine oil or clean fuel before sliding it into place—this prevents the rubber seal from pinching, twisting, or tearing during seating, which would cause an instant fuel leak. Maintenance Advice: Always use fresh, stabilized fuel and clean or replace your primary fuel pump filter periodically to protect your new injector from premature contamination.
