Originally made from Mikuni these carburetors are specially modified from Sato Engineering for freestyle engine applications.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. These carbs are available from Sato Engineering in Japan and the particular model is the Masaki Wake edition (JJSF 4rth Pro Freestyle 2009).
