Big Bore Pistons And Cylinders - 94mm machine in for 78 or larger stroke Mahle

All kits come with pistons, cylinders, rings, wrist pins and clips. Many of the kits will require machine work to the heads and case. Before you buy a kit, you should have a good understanding of how to set the compression ratio. Many people think that bigger motors are unreliable. This is just not true. When a motor is properly designed and built, it can be very dependable. You will not realize the full potential of the bigger pistons, unless you run big valve heads. There is a lot of information needed, so call us and we will gladly help. Note: The only thing we don't like about these kits are the rings and the wrist pin clips.
