Home > E-Z Bore Equipment - Portable Cylinder Boring Machine
E-Z Bore developed a portable align-boring system to fix a common problem found in production small engines. Basically production engines used in performance applications are designed for very low steady RPM's. Once this engine is adapted into a performance application the misalignment between the cylinder bore and the crankshaft becomes a major factor in the overall performance of the engine. These small engines are produced in massive numbers with the block and crankcase cover produced completely separate from each other. Once these two pieces are assembled, the cylinder and crankshaft alignment can be very good to very poor, thus the reason for 2 identical engines that perform completely different from each other.

E-Z Bore has been specializing in performance small engine cylinder work, both in-house and with our boring equipment for over 30 years. If you're racing a small engine, then you need to get to know the E-Z Bore team!
