More OEM bloopers

Yamaha, in its industry leading online mechanics training, Yamaha Technical Academy (YTA) describes engine crankcases that separate left to right as "horizontal split," while the rest of the industry calls this vertical split, and those that separate up and down as "vertical split," while the rest of the industry refers to these as horizontal split. Yamaha also has a hard time keeping things simple in the electrical area, commonly referring for example to a permanant magnet alternator as a "magneto" alternator, terms reminiscent of ignition systems. Speaking of magnetos, all but one or two of the powersports industry's many OEMs fail to distinguish between energy transfer and magneto systems, referring to both as magneto. Energy transfer is a 3-coil rising field system most common on off-road motorcycles, magneto is a two-coil collapsing field system found mostly on stationary engines.
