reed valve and transfer bowls were in-house flow tested and dyno tested to produce as much power as possible

To start we machine the cylinder for the 2mm stroker and for a proper squish clearance with out stacking gaskets

there is a lot more that has gone into these cases than most will realize

6700 - G290RC +2mm BALANCED Crankshaft Between the help of DaveOBR balanced crankshaft for 30. 5cc engines. Our cranks are CNC machined before being pressed back together and hand trued. Balance factor is greatly increased over stock and you can expect more power across the board along with a huge drop in vibration. From our testing we see engines with a balanced crank spool up quicker, have more mid range power and rev higher.< p> <p>< p> <p>All balanced crankshafts have a lead time of about a week. If your
