When staying with the remanufactured cylinder:
Due to the fact that a large number of our customers do not return their cores (which depletes our inventory and cannot be re-plated for the next customer), we require you to Send Your Core to us before we release your order. Please make sure it is NOT sleeved (if it is, we will not be able to fulfill your order). Please remove to ALL fittings including studs, power valves, etc. as our cylinders are shipped completely bare. Please avoid any damage to gasket surfaces when removing these items as it could result in a repair fee.

MCB Performance specializes in only engine components and rebuild kits. We've been doing this since 1994 and we refuse to sell parts that are not proven, and that are not of a standard we would use.

The MCB/Wossner crankshaft and cylinder that can be selected as part of this kit is made of premium materials and a bearing that exceeds OEM specifications. The cylinder has better casting features and cleaner more precise port shapes and chamfers than OEM!! It's something that you have to hold in your hands yourself to understand.
