O.S. ENGINES SPEED TUNED .21 VZ-B V-SPEC AL ENGINE

O.S. ENGINES SPEED TUNED .21 VZ-B V-SPEC  AL ENGINE

A new version of a popular powerhouse! An aluminum heat sink head combined with special factory tuning makes this a more efficiently cooled .21 VZ-B V-Spec competition engine! The specially coated crankshaft features a precision ceramic bearing that greatly reduces friction – plus a Tungsten weight for added balance. A double adjustment carb allows for ultra-fine tuning for demanding race conditions. Aluminum transfers heat away from the crankcase more efficiently for more consistent cooling. Available separately, the T-2060SC WN tuned silencer (OSMG2938) utilizes a welded-on pressure nipple and was developed specifically for this engine.
