Description
If you're running a mildly modified Yamaha 4125 with aftermarket pipes or filters, your carburetor jetting is likely holding back performance. The DYNOJET Stage 2 Jet Kit recalibrates fuel delivery to match your modified intake and exhaust, unlocking approximately 8% more power while improving throttle response and overall drivability. This is a bolt-on solution that delivers measurable gains without requiring engine internals work.
The fully adjustable design lets you dial in the perfect air-fuel ratio for your specific combination, whether you're chasing track performance or smoother street riding. Installation is straightforward and doesn't demand professional tuning—just follow the included instructions to swap jets and clips in your existing carb.
