Try the left side of the crank.

um no there is no flywheel. ive checked my service manual and there is NO fly wheel.

infact my dad can only name 4 bikes that do have one. bikes dont generally have them. due to, they dont need them!

purpose of a flywheel is to store kinetic energy for when large amounts of resistance is encounterd (taking off from a standstil) to prevent the engine from stalling. so you mainly see them on cars and very big bikes. bikes dont have this problem because their power output is greater than the resistance they would encounter.

and i dont have a "bogging" down problem my rear wheel is lighting up half the time and my front one gets carried a few metres before i change gear.
but yes your right in most cases ducatilover you do take the revs above peak torque. but its not needed on mine (ive tied and all i did was burn out for a second or two before she took off

[Ooky]

what would jesus do :P

be so annoying you would want to nail him to a cross?

[Crasherfromwayback]

Then he's as blind and as simple as you are. Even my Moto-x bike has one...as they all do! Look under Rotor.

[Hiflyer]

As Slyer said a while back. If you can do a burnout on a 250 with no front break you probably need new tires :P

[Ooky]

you say that like there is a problem with the hyo's OEM tyres

[gatch]

um no there is no flywheel.

You are taking the piss aye, if your dad can only name 4 bikes with a flywheel, then he only knows of 4 bikes, even moto gp bikes have a fly wheel.

Did your father name the NSR, it has a flywheel, so does my scooter, and my friends Ninja 250, CRb, Ducati, are you sure he didnt mean that there are only 4 bikes that dont have a flywheel.

Also the Hyobag GT250r does indead have a flywheel, which anyone with basic engine knowledge should know, you will find the part number is 32102HJ8200 in the GT250R Parts Catalogue.

fly-whels balance the motor and give it torque.......


please chaos rider your realy making yourself out to be an idiot........
stop pretending you are a professional racer and stop pretending you know about motors when you dont even think bikes have flywheels!!!

[Ragingrob]

Lololololololol

wait


LOLOLOLOLOL!

[Harvd]

Ooooh ive figured it out, He is just taking the piss


(i hope he is...)

otherwise I want vids of these burnouts and wheelying from a whopping 36!!!!! claimed hp. I was on a rgv250 yesterday and it was only feeling light at top revs full throttle in 1st. (read not wheelying)

[SS90]

Oh no.

It's happening again.

1) Chaos rider, your bike has a flywheel.

what you and your dad are getting confused with is on a car, the clutch is PART of the flywheel (which is a large plate, surrounded by a gear, which allows a starter motor to turn it when you turn the key.

so, a car "flywheel" is 1) a large rotating mass to store kinetic energy between the 720 deg of engine rotation that a 4 stroke has

2) a large steel clutch plate

3) a starter gear

All in one

Motorcycles that have the same system are

MotoGuzzi,BMW's, and Arial's.

Every engine has some sort of flywheel.

Your Hyosung does. The "Flywheel" has 3 functions.

1) a large mass to stroke Kinetic energy between the 720 Deg of engine rotation between each cylinders power strokes

2) it holds the magnets of your rotor (part of your charging system) on the inside

3) it has the trigger points for your ignition.

In the quest for more acceleration (at the cost of low RPM torque) many racers will remove the flywheel, (and build a trigger wheel for ignition), the resulting loss of rotating mass will allow the engine to rev out faster, but is only suitable for HIGH REVVING 4 CYLINDER bikes (not your Hyosung)

It's a Vtwin, it needs to store kinetic energy between it's firing strokes, and also it is a low revving engine.

The ideal weight of your flywheel is a function of it's number of cylinders (how many times the engine fires in 360 deg of crank rotation (4 cylinder engines obviously fire more times on a given number of crank rotations, but, because each cylinder is smaller, the power stroke is weaker than the equivilent 2 cylinder (2 125cc cylinders firing each 720 deg) opposed to 4 75cc cylinders firing each 720 deg....... as they say, there is no substitute for revs!

as well as how many degrees apart each cylinder fires, for example, (in the case of a vtwin), do the cylinders fire at the same time, or 180 deg apart?

fire at the same time, you need a heavier fly wheel (and an engine set up that makes the most advantage of the available torque) fire 180 deg apart, and you are better suited to an engine set up that is higher revving...........

In short, essentially EVERY SINGLE INTERNAL COMBUSTION ENGINE HAS A FLYWHEEL.

I hope that helps.

On a personal not Chaos, to learn something first you must admit you don't know anything.

Enthusiasm is a great thing that comes with youth!

[ducatilover]

find me a fly wheel in a hyosung and ill start listening to you

and no one knows why a bumble bee flys, its wings are too small and as far as physics are concerned it shouldnt

i dont care what my spelling is like i have more important things to worry about. like trying to teach you that you know nothing about the hyosung and you need to shut up and go take one apart.

I'll find it, it's what your clutch grips. You and your Father are in desperate need of some education. As I said, been there done that Dear child. I make the most of my time by trying to pass on information I have acquired through the experiences I have had, to dim witted twats like yourself.

Try the left side of the crank.

No kidding....

Actually, that is an urban myth. Science knows how the bumblebee can fly (and has known since 2001), it can fly because its wings encounter dynamic stall in every oscillation cycle.

Also I true.

um no there is no flywheel. ive checked my service manual and there is NO fly wheel.

Your bike can NOT do a wheelie and skid at the same time. My bros650 was not a very powerful bike, only made 60 odd hp at the wheel after the jetting and exhaust was on her, I ran an 11.8@183km/h on her and it didn't wheelspin once from a launch nor did it need to lift the front much at all. With the whole 24nm your pathetic and asthmatic bike makes I very much doubt it would wheelie or wheelspin from a launch, especially if you load the gears up like an idiot.

Oh no.

It's happening again.

Shortened your post, you as usual are right. I agree completely

Now I must hop in my 73 bmw I have tuned with my nose, it has no flywheel and does great donuts in 5th gear even though it's really a four speed. I include a picture to prove it's awesome and really like got no flywheel and it made the bumble bee fly.

Stop being a fuck wit and listen Chaos.

[R6_kid:Me]

Because real-estate in bike engines is scarce they usually try to save space by combining parts that do a similar jobs. The fuel and water pumps sometimes share the same housing for instance. In most/many/nearly all bikes the rotor is incorporated into the flywheel, generating electricity by spinning magnets around the stator (winding of electrical wires) as well as keeping the motor spinning. On a car the flywheel does it's job by itself, while a belt drives the alternator to generate electricity for the car.

Will your bike be race ready for Nov 1st chaos, Have you got 1 piece leathers or 2 piece that zips together(1 piece is better), a back brace ,and can you get a MNZ day license from AMCC or do you need to get one( club $75? or full $125?) of MNZ , you want good gloves with armour on the knuckles and race boots too, road boots dont handle the abuse they get on the track, when you come off(which we all do) its amazing were your gear gets marked and were you contact the track, i wrecked the zip on the inside of my left boot, dont know how but you can see were the inpact was and it was a slow low side. GET GOOD GEAR ! Have fun and go hard Chaos, shame i wont be there, will be doing the Post classic GP onr Oct 31st and Bike Rider Magizine Summer series 1st Round (Pacific club) the day after , both at Taupo

My bike(s) all have flywheels/rotors , maybe its just not called a flywheel in the husung book


EDIT http://www.kiwibiker.co.nz/forums/sh...d.php?t=105966 October 4th is the new date for AMCC round, C u at Taupo on Nov 1st chaos, 5 and a half weeks to go before Puke

hey duatilover... i hope you know that they are NOT tractors!!!!

someone sold you a NONtractor.....

sorry to break this news matey
