The lean because you initiate the counter steer to initiate the lean to initiate the turn




we know the positives of a counter-rotational hub to neutralize the rotational mass inherent within spinning wheels what besides weight would be a negative of the counter-rotational hub?

Possibility of planetary gear failure under load, such as braking with those funky counter-rotational brake rotors.

Re: blu-ray and hd-dvd, licensing issues prevent the two technologies from being combined in the same device.

How does a six-stroke engine work?

(They already have dual Blue Ray HD players they are treating it like the multiplatform DVD/ VHS players so they already have precedence for a mixed Blue HD Player)

water is injected into the 5th stroke expanding from the residual heat of the 1st through 4rth stroke until the 6th stroke clears the steam

What is so beneficial from adding the 2 more strokes

Interesting re: blu-ray/hd-dvd, didn't know that.

The extra two strokes turn give an extra power stroke, since steam takes up approximately 1800 times the volume of liquid water, and avoids an addition of an extra power-robbing compression stroke. Water is injected at when the piston is at TDC after the exhaust stroke, the water boils and creates a power stroke, and then the steam is ejected with another exhaust (upward) stroke.

Why are there problems with this engine and cylinder durability?

Rapid changes in heat / cooling from the rapid expantion of the steam instead of the steady heat of the normal heat cycle of the motor the 6 stroke goes through a rapid heating cooling cycle in fact the article i read the gentleman who invented it had his hand on the motor while it was running and said it was warm


How does and Intercooler work?

Close I'll give a hint, it has to do more with chemistry than simple thermodynamics.

I'll lay off the intercooler question, at least til the correct answer about the durability comes up

Come on kids let's get someone other than me or KMD in on this!

What is included valve and angle and how does it effect engine performance?

I assume you mean "included valve angle" and it is the angle of the valve stem from verticle. It affects engine performance by affecting combustion chamber shape and design which affects combustion efficiency which is the main factor affecting output per unit displacement.

Why is a male slider fork design superior to a female slider fork of the same tube diameter?

I'm not familiar with the vocab. Does male slider mean conventional and female slider mean upside down?

I was asking about the mechanical chemical process not what it does but how it does it And i may be mistaken but i thought the intercooler works on the chemical rather than the compression factor

The male will always be superior due to the fact the male is a solid while the female is a hole (Mechanical wise)

I ssume you're being facetious.

Male slider is the "upside down" fork, female slider isd the conventional fork design. slider refers to the part that moves.

There are benefits to both designs so I don't know what your getting at. I'll list benefits of upside-down forks and you tell me if one is right.

1. Stiffer/stronger because the larger tube assumes the greatest point of leverage.
2. Because the upper tube is the outside tube the lower tube stroke can go almost to the cap. This allows for increased travel and/or less bind due to the lower and upper bushings being spread far apart. Conventional forks can be hung below below the front axle by moving the axle to the front of the fork rather than the bottom but ground clearance problems can result depending on the type of bike/riding.
3. They look cool

I could go into valving and but I don't think thats what you're after.

I have no idea what your talking about. A super or turbo-charger compresses air. The compressed air is very hot and cool air is better for combustion. The hot air is forced through a intercooler to be cooled before being pushed into the combustion chamber. An intercooler is basically a heat exchanger like a radiator or heater core.

Its all about expansion and compression. If you expand air it cools, if you compress air it heats up. Try by pushing your lips closed and blow into your hand, the air that escape from the small passage is expanding as it exits and will be cold. Compare it to opening your mouth and breathing out.

Was he looking for the "unsprung weight"? I've always belived that was the reason for the upside down fork.

Cold air=more dense air=more O2 available for combustion. (simply put)

Super! Valving, as in cartridge vs. damper rod does play a big part also because the "upside down" forks weren't available until cartridge type valving was invented. damper rods need to be immersed in oil to work and they wouldn't be in the upside down fork.

Speed_Demon was the closest on the cylinder wall. I'm not a metallurgist, but from what I understood, over long periods of use, the hydrogen will react with iron in the steel cylinder jacket and develop microscopic cracks.

new question!!!!!

Woudn't nikasil or ceramic coating mitigate that?

How did octane ratings get their start? Why is it called an "octane rating"?
