DYNOJET Jet Kit - Kawasaki EX250 2138

The DYNOJET Jet Kit is engineered to unlock your EX250's fuel delivery potential, delivering measurable power gains from 5% to 15% depending on your engine configuration and intended use. Whether you're optimizing a stock motor or running a race-prepped build, this fully adjustable solution compensates for intake and exhaust modifications that would otherwise leave your bike running lean. With multiple stages to match your setup, you'll gain both peak power and refined driveability without sacrificing reliability.

DYNOJET's stage-based approach means you're only paying for the tuning you actually need. Stage 1 works with stock or mildly modified setups, Stage 2 handles upgraded filters and pipes, and Stage 3 pushes toward the upper limits of bolt-on modifications. For serious competitors, Stage 7 delivers maximum power in a race-only package optimized for high-RPM operation.
