"Rust bluing" and "fume bluing" provide the best rust and corrosion resistance as the process continually converts any metal that is capable of rusting into magnetite (Fe 3 O 4). Treating with an oiled coating enhances the protection offered by the bluing. This process is also the only process safely used to re-blue vintage shotguns.
At low engine speeds, the wave pressure within the pipe network is low. A full oscillation of the Helmholtz resonance occurs before the exhaust valve is closed, and to increase low-speed torque, large-amplitude exhaust pressure waves are artificially induced.
The Honda NSR250R is a street-legal road-orientated 249cc two stroke sport bike produced by Honda Motor Co., Ltd between 1987 and 1999.. It evolved from the popular NS250R MC11 and was produced over four distinct generations, each powered by liquid-cooled, reed valve inducted 249cc 90° V-twin two stroke engines.
Bluing (steel) is a passivation process in which steel is partially protected against rust Bluing may also refer to: Bluing (fabric), a blue dye used to improve the appearance of fabrics; Bluing (hair), a blue dye used to improve the appearance of hair "bluing" of machine parts to check for tolerances, see engineer's blue
The layout of a 4-2-1 system is as follows: four pipes (primary) come off the cylinder head, and merge into two pipes (secondary), which in turn finally link up to form one collector pipe. [ 2 ] Compared with a 4-1 exhaust system, a 4-2-1 often produces more power at mid-range engine speeds (RPM), while a 4-1 exhaust produces more power at high ...

Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting.
