Ok I was just looking at specs of both bikes and notice the engine specs. What is the difference between an Inline 4 and a 4 stroke. I would think they are the same, both have 4 cylinders, correct? Can some one help me out? Thanks!
LOL, i am sure that some people just the four stroke works like this
-combustion
piston goes down (1st stroke)
piston comes up (stroke 2)
-exhaust is expelled
-fuel is drawn in
piston goes down (3rd stroke)
piston comes up (4th stroke)
-compressed fuel and air gets spark and combustion again
-repeat.
Ok I know what an Inline 4 is, just wasn't sure what a 4 stroke was. So does the FZ6R still have 4 cylinders as it has 16 valves? And how exactly does the Inline 4 fire?
NO
first is intake ( combustion is NOT A STROKE ) where air and fuel is drawn into the cylinder via vacuum
compression ( where the fuel air is compressed )
power stroke ( a result of the combustion ) the fuel air mix is actually ignited before the piston reaches TDC
exhaust stroke
Ok so I understand it easily a 4 stroke means the pistons make 4 revolutions before the spark plug fires again. If both bikes have inline 4's and both are 4 stroke why did Yamaha list them differently.
Engine Type
FZ6 - 600cc liquid-cooled inline 4-cylinder; DOHC, 16 valves
FZ6R - 600cc liquid-cooled 4-stroke, DOHC 16 valves

wait, what? what did i say that wasnt repeated by you except that you just had the first set of stokes differed from my first set?
i was not saything that combustion happens while, i was just simplifying by showing after the combustion, the piston is pushed down into its first stroke.
Good question... :thumbup: The simple answer is yes, they are trying to describe roughly the same engine.
The "in-line 4" refers to how the cylinders are oriented. In this case it means all 4 cylinders lie on the same plane or in a row instead of a V-8 or V-twin where the cylinders are anywhere from 45 to 90 degrees relative to one another (probably other angles too).
The "4 stroke" refers to how the engine produces power. There are lots of different ways but the most popular on a motorcycle are 2-stroke (mostly off road bikes these days) and 4-stroke.
The 4-stroke specifically refers to the 1.intake 2. compression 3. power and 4. exhaust strokes. Each step takes 1/2 of a full revolution (or 1/4 of a power revolution for the gear heads). The 2-stroke makes the process more concise and is much more powerful for the weight of the engine but not fuel or environmentally efficient.
Bottom line is both the FZ6 and FZ6R are both in-line 4 cylinder, 4 stroke engines. I'm not sure about the rest as for which has more power, higher compression ratios, or larger bore or stroke etc... Maybe someone else can help with other details.
Bring back 2-Stroke engines I say. :ban:
