DYNOJET Jet Kit - Honda XR650L 1148

Carburetor tuning is critical for extracting maximum performance from your Honda XR650L, and factory jetting rarely accounts for modifications or riding conditions. The DYNOJET Jet Kit delivers precision fuel mapping with fully adjustable stages, letting you dial in the exact air-fuel ratio your engine needs—whether you're running stock components or a heavily modified setup. Depending on your build and intended use, you can expect measurable gains in both power output and rideability, from a conservative 5% bump to a race-focused 15% improvement.

Choose Your Stage:

• Stage 1: Stock engine, 5% power increase
• Stage 2: Mild modifications, 8% power increase
• Stage 3: Individual air filters, 10-15% power increase (street rideability may suffer)
