Intake manifold to mount the OKO or Mikuni carbs. Holes are 60/62mm center to center on engine.
Great fit and gets the job done. This intake as well as a deeper throat have been used on teh Cleveland Cyclewerks bikes with great results.
Getting the fuel and air flow correct when upgrading your carb always consider carb, intake manifold, air intake and/or air filter or velocity stack being used. The right combo with jetting gets great results in torque and top end.
