Engine Cylinder Boring & Overboring Experts
Since 1940, US Chrome has made cylinder bores our business. Our cylinder boring services keep engines running at top performance, ensuring burr-free and straight-as-an-arrow cylinders. The expert technicians regularly restore worn or distorted cylinder bores back to OEM status. For riders looking for more displacement, our cylinder overbore process has made us a leader in the industry.
Overboring can lead to cylinder distortion due to lower wall thickness. Excessive overboring can make walls too thin to withstand combustion pressure and piston side load. The cylinder boring experts at US Chrome understand appropriate limits and ensure safe boring.
Boring your engine isn’t just for riders and racers who want more power. Over time, you can experience a loss of power because of flat spots on the cylinder walls or because the diameter is out of spec. Cylinder boring is just one of the cylinder repair services US Chrome offers.
