every one calling this kid stupid but no one can answer him....lol


very very simplified but the biggest reason is weight and distance..

smaller lighter crank , connecting rods and pistons with a short stroke can spin alot faster with out breaking then larger heavier crank , connecting rods and pistons with a longer stroke..

the stroke is how far the piston moves in the cylinder

 

hey no one asked you old man. hi roger. did u miss me??????

 

i was ok with this kid(ben) until now..... here's what happened omr... he originally posted some **** about if he has a 75% average, then what does he have to get on his final to pass? SERIOUSLY!
and then, after a couple responses(one from me and the other from $$$$dino$$$$) he changes that **** to say something completely different. wtf!


fyi- my post saying ban was in response to his original post.

 

Straight fooled me on that one. Damn... Im gonna go Kill myself now

 

HaHa i surprised myself with that explanation i came up with....

 

 

dude... that is like the time I convinced a kid he blew a power band gasket in his car which caused the muffler bearing to go bad causing it to smoke. I also let him know that the AC/DC Aletenator Deltanator could have been burnt up.

yours was much more superior!

I would have let that one roll and see how long it took someone to call me out!

 

there is some truth to your made up explanation.,

a motor with a longer stroke will have more force put on the side of the cylinder by the piston because the connecting rod will be pushing and pulling the piston from the side more then a motor with a shorter stroke..

the motor with a shorter stroke will keep the bottom of the connecting rod closer to the center of the cylinder hence pushing and pulling in a straighter line..

what you were saying about the angle of the cylinders was completely wrong though , opposing cylinders are way more efficient then inline cylinders but take up way to much room for most applications ..

in an actual flat motor with the cylinders exactly opposing one another one piston going down will be pushing another piston up via the crank and wasting less energy then a v motor or in line motor which actually pushes the crank down on to the main before converting the energy to lift another piston up ..

 

yo u ever think about how a rotary motor works? that ***** pretty cool.. i did a report on em in high school

 

I think he missed the spelling in the title..

it's supposed to say mEth.




stop smokin it!

LOL

 

yea i know its crazy how this stuff works but its awesome how if you make it sound like you know what your talking about you can fool people into anything. the power of a convincing explanation is amazing lol. i once convinced a kid his piston return spring was worn which is why is 2 stroke didnt have as much power as it used to.

 

SWEET HOTTNESS

 

I am stealing that from you!

 

It comes down to what the engine is gonna be used for. A high displacement v-twin doesnt need to turn 14k rpm to make power because of its size. Most v-twins are designed for the street so there cam timing is set for the engine to make power down low. The more power you make at low rpms the more "streetable" the engine is, and low rpm torque or "pull" is what v-twins are known for. Most sport bikes are designed for the track and would therefore spend most of there life at Wide open throttle. When your WOT all the time its good to make most of your power at the top of the rev range so you can stay in the "meat" of your engines power band. What makes it make power up top and not down low? It all comes down to cam timing, thats why
your bike sputters at 2k rpm where a v-twin would pull hard. Cam timing, thats why cars made for drag racing barely run at idle but make 1000hp at 8-9k rpm. Now im not saying there arent other factors, but thats the major one. Also, v-twins are stereotypically low revving, but dont have to be.
Ducati runs a standard v-twin in moto-gp. Suzuki used a v-4 engine just like honda did for years. Speaking of honda they used a v-5 in the famous and hugely successful RC211v. I realize the original question was about twins.

 

you guys are just hating and are jealous hes sponsored by hindle now

 

Haha alright but when you use it after your done saying it you have to say courtesy of Stuntin73

 

LMFAO

 

bump

 

haha no problem. I Give credit where credit is due!

 

cam timing has nothing to do with why an inline 4 revs so much higher than a v twin now if your talking about duration and lift then yes they are variables but the main reason is most v twins have huge *** pistons and a long stroke ..
