Intake Manifold- Minarelli-Yamaha-Jog with Reed block to add more gas when needed doing upgrades works on all 40QMB two stroke engines.

This is the intake to get for the Yamaha Zuma.

We used this manifold with high performance carb on a RX8 with an E140 Linhai/Yamaha engine with great results plus the Vento Zip and Triton R4.
