Dynojet jet kits are one of the most effective upgrades you can make to a carbureted motorcycle, ATV, or dirt bike. Designed to correct lean factory fuel settings and optimize air/fuel ratios, these kits unlock stronger performance throughout the entire powerband.
Benefits include: Noticeably quicker throttle response
Increased horsepower and torque
Smoother, more consistent power delivery
Reduced hesitation and flat spots
Cooler, more efficient engine operation
Often improved rideability and fuel efficiency
From the factory, most carbureted engines are jetted lean which limits performance and responsiveness. Dynojet kits recalibrate the fueling to match real-world riding conditions, allowing your engine to breathe properly and deliver the power it was designed to make.
Each kit is application-specific and typically includes: Precision-machined Dynojet jets
Adjustable needle(s)
Drill bits (when required)
Detailed, model-specific installation and tuning instructions
Dynojet kits are engineered and tested on dyno equipment to provide predictable, repeatable results with common modifications such as aftermarket exhaust systems, intake upgrades, or airbox changes.
Whether you're looking for sharper throttle feel on the street, stronger midrange for trail riding, or improved top-end performance, a Dynojet jet kit delivers a proven, reliable tuning solution trusted by riders and race teams worldwide.
