Ninja Terminology

Seems like every time someone has a problem with their Ninja they use a totally different language to describe the problem. For example, "It cranks over but it don't turn over" – which is a totally meaningless description. When asking for help online, people need to be precise and technical. So I decided to list out the proper terminology to use when describing problems with the Ninja (not that it ever has any :-) ).

Crank – This is the act of attempting to start the engine in the normal manner. When an engine is cranking, the starter motor is running and spinning the engine. The engine does not have to start in order to crank, but it does have to turn over.

Turn Over - This is when the engine crankshaft rotates. It can either be by cranking, by rotating the crankshaft manually or by other means. The engine does not have to start or crank in order to turn over.

Start – This is when the engine is turned over and begins to run on its own. The method used to turn the engine over is irrelevant. The term "Wont Start" means that the engine will crank normally, but not run.

Bump/Push Start – This is when the engine is turned over by using the wheels rather than the starter motor. Since it is not the normal way to start the engine, it is not the same as cranking. For example, when the engine wont crank, you can push start the bike to get it started.

Run – The engine is turning over under its own power.

Engine – The thing on the bike with a crankshaft and pistons that propels the bike.

Motor – The thing on the engine that cranks it.

Starter – This is the motor.

Solenoid/Starter Solenoid – This is a high amperage relay located on the right side of the bike next to the fuse panel. It has explosed electrical nuts that connect the positive battery terminal to the starter. For testing purposes, these nuts can be shorted to crank the bike.

Break - The act of ruining something.

Brakes - The mechanical devices on the bike that cause it to stop.

I will add more as I come across them.
