After a long search, we’re excited to finally offer these manifolds!
Designed to run hotter for improved performance, this manifold does not feature cast-in cooling. This approach has shown to yield better power results on the dyno for Yamaha engines, thanks to a tip from Tim Tynan.
These manifolds fit the Yamaha 701 Superjet (61X) and 650 Superjet (6M6) engines. The header pipe hole measures 46mm, and the manifold opening is 45mm, with ample material for further modifications.
They are also compatible with 62T and 64X engines, though you’ll need to install helicoils to fit them.
Price includes worldwide shipping.
