Originally made from Mikuni these carburetors are specially modified from Sato Engineering for freestyle engine applications. They are bored from 46mm to 49mm and the overall body height has been reduced in order to increase mixtures velocity. Also, they incorporate tiny holes that provide a fuel shower which results in better air/fuel mixture. The pictured carbs are designed for the Yamaha freestyle engines and provide instant acceleration and precise throttle control. The particular model is the Hiroshi Watanabe one, the JJSF 2009 Pro Freestyle Champion. The carbs are available from Sato Engineering in Japan.
