An internal combustion engine is the heart and soul of your motorcycle. No matter which type of motor your machine uses, all of its parts must work together perfectly for your bike to run. The main parts of a motorcycle engine is a crankcase holding the crankshaft, engine block with cylinders, and a cylinder head that is mounted on top of the cylinder block forming the combustion chambers. Also, a cylinder head holds the inlet and exhaust valves providing a well-timed delivery of the fuel-and-air mixture and exhaust gases removal. It also houses all of the valve springs, spring seats, retainers, shims, and shim buckets.
A cylinder head can be damaged in case of a catastrophic engine failure with bent valves or broken piston. It is crucial to replace a malfunctioning component as soon as possible to avoid complete engine breakdown resulting in much more expensive repairs. When it is time to rebuild your engine, visit our online store to find an assortment of premium motorcycle cylinder heads and related components by only reputable manufacturers. We work with such well-known brands as Arlen Ness, Feuling, Biker’s Choice, Stevenson’s Cycle, Cylinder Works, and many others. At our website, we offer complete cylinder head rebuild kits, rocker boxes, studs, bolts, gaskets, O-rings, and more.
There are several signs that can indicate that your engine needs something more than a regular oil change. If your valves are badly worn or even stuck, it would be difficult to start the motor. Also, check if there any oil leaks around gaskets. If you see white smoke coming out of the exhaust even when the engine is hot, it may mean that motor oil or coolant leaks into the combustion chambers through head gaskets and valve seals. In that case, you may also notice excessive oil consumption. When you find large metal bits in used motor oil during regular maintenance, it is a sign of internal damage, which needs to be addressed promptly.
