6306 - Billet Crankcase For G320RC/G340RC Engine

<p>This crankcase only fits the Zenoah G320RC/G340RC engine! We've clearanced the inside of the crankcase for a +2mm stroke. You can expect a small gain in performance by just installing this crankcase. We've removed the excess volume from the crankcase to help with throttle response. Transfer bowls have been changed to help with flow and oil holes have been added to prolong crankcase bearing life. Cases come complete with nachi crankcase bearings, snap ring and oil seals installed. Just like our other cases we went with a 3 piece design. If you're ever to crack the fan cover mount it can be replaced by itself instead of having to purchase a complete crankcase. There is not a gasket that seals the two case halves. A good gasket sealant such as threebond 1211 needs to be used.</p>
