Jetworks Lvl Kit - Yamaha 701 - Lvl 0.99

We’re proud—and honestly a little surprised—by how well the research and development of the LVL 0.99 Kit turned out. We started developing it back in 2020 when Factory B-Pipes were nearly impossible to get, even though we were one of the few dealers still carrying them. By the end, we went almost three years without fresh pipes, right when everyone wanted to mod their skis. For older models like the Yamaha Wave Blaster, where pipes aren’t made anymore, used ones are rare and expensive.

This kit honestly outperforms a basic bolt-on pipe, rejet, and air filter setup. It’s designed to maximize low-end and mid-range pull without chasing big top-speed gains.

The kit turns any Yamaha 701— both single-carb and twin carb models—into a blast to ride, whether it’s a WaveBlaster, SuperJet Or even the elusive FX-1.

We bump compression for better pump gas, improve the intake for better breathing, dry out the exhaust for sharper response, and tighten the exit to carry more RPM up top. The real magic, though, is our custom big-hub swirl impellers—we pick the right one based on whether you want max low-end or balanced all-around performance.
