Every Dynojet carburetor jet kit is designed specifically for your machine to increase engine power, smoothness and throttle response. Each kit provides optimum performance throughout the rev range for maximum power and optimum fuel economy.
PartsGiant has a variety of jet kits on hand to meet your specific riding needs.
Choose the correct kit for your needs:
Stage 1 jet kits
Ideal for motorcycle & ATVs with a stock engine using the stock airbox, air filter and stock pipe. Stage 1 kits are fully adjustable to work with well-designed aftermarket pipes as well as stock replacement air filters.
Stage 1 kits improve throttle response and driveability. In most cases, power increases of approximately 5% throughout the entire power range can be achieved with correct tuning.
Stage 2 jet kits
Suitable for machines with a stock or mildly tuned engine that have a well-designed aftermarket pipe, a modified airbox and a stock replacement air filter.
Stage 2 kits are designed for applications where individual filters cannot be installed or for applications where airbox modification improves the engine's performance. In most cases power increases of approximately 8% can be achieved with the correct tuning of your carburetor.
Stage 3 jet kits
For installation on machines with stock or mildly tuned engines using a well-designed aftermarket pipe and individual, pod-type air filters. In most cases power increases of 10-15% can be achieved. Mind you, driveability may be compromised particularly with short stroke, high-RPM motors. So long as you're keeping the revs up, this usually isn't a problem.
Stage 7 jet kits
For race only use or for special applications, like the Yamaha V Max complete induction kit. Stage 7 kits are designed to optimize jetting for a given tuning specification or racing conditions.
