shifter kart....

[jr dragster T]

Depends all on engine, 2 stroke, 4 stroke, porting, exhaust, carb, etc. If you have to ask these questions i dont think youre ready for a build like this.

Exactly. A 80 cc engine wont cut it for what you want to do! I have ridden a 125 cc 4 stroke 4 speed manuel bike and its pretty impressive but even that wont realy break 2 kart tires loose unless the tires are like plastic. Sure on the bike I can lift the front wheel with a blip of the throttle from a roll in 1st gear. But it wont be enough power to smoke the tires and go 75 MPH. The bike does around 50 MPH with a pretty small rear sprocket and thats REALY ringing out the motor ALOT. PS Just ask me...Peformance does NOT come cheap. And plus your not ready to build something of that caliber yet.

You may want to consider something more simple...like a souped up Briggs or something

It's really not that much more difficult to set up a motorbike engine. One more cable for a clutch, and a lever for gears. If you can rig up the throttle cable (which you need on a Briggs) then you can rig the clutch, and the gear lever is easy as.
I don't know how anyone else feels but I would much prefer gears over any automatic transmission (cent. clutch or torque converter).

The point i was trying to make was that a 80cc engine WILL work for what you want to do.Depends on what kind of engine though. Like i said, the Kawasaki KX80 dirtbike makes 20hp, its a 2 stroke. It would spin the tires EASY. They wind out like hell too so your'e gunna have great top end. And thats a 80cc. I say learn a bit more about this stuff before you tackle something of this magnitude smokin....

Ah, it's a bit more complicated than that. You need welding skills (motor mounts, linkage mount, etc.), some mathematical knowledge (calculating final drive ratio, sprocket selection, etc.), and so on. Definately not a bolt-on affair.

Wow

This is by far the dumbest thread I've ever read!!! Are you all retarted? It's so bad, I registered just to tell you all this!

I don't even know where to start!

Smokin... what are you smokin!?!? You obviously have the internet, ever tried google? Or do you prefer to repeat stupid questions in a thread hoping that one of these other idiots will state the obvious for you?

and whoever said to stick with air cooled and 200cc, what century are you living in?

To answer, an 80cc water cooled 2-stroke is fast as **** in a kart. Not as fas as a 125 obviously, but it will definitely burn the tires off the thing!

I can't believe I'm wasting time on this. Clearly you couldn't build a box, much less a kart from scratch. Try google, it's great!

 

[Kaptain Krunch]

You just wasted your time signing up and making a post to tell us that WE are retarded?

 

[freakboy]

suck a dick

 

[modelengineer]

Oh, no. THE TROLLS ARE HERE! (Well, one is...)

If you're so great, post a pic of your kart. Your silence or lack of pics will result in confirmation that you're full of ****.

What's wrong with air cooled motors? I use a 2007 Suzuki air cooled motor. 50hp.

 

[freakboy]

i use a 20 hp air cooled motor in a racing mower and a 6.5 air cooled in a gokart and they work fine.

 

[Rickracer]

He's right about the KX80 motor though, a friend of mine has one on a shifter kart, and it will smoke the tires and run AT LEAST 60, we haven't had it anywhere that faster would be safe enough.... yet. It is FRICKIN FAST though,
Water cooled 2 strokes are BAD TO DA BONE, blow away most 4 stroke motors over twice their size, and weigh half as much.

I have a blown up ktm65sx motor and depending on how fast it is Im going to rebuild it. It should have about 15 hp when Im done. Do yall think this will be big enough for a shifter kart frame or is it a waste of time? Yes its air cooled and is 65cc

 

[science5252]

dude, are you serious?
I may only be a noob (ha ha), but we arn't here to do your homework and research for you, but to help you if you get stuck. To put it simply, you can't make a real racing kart. But if you want to make one that you can drive around and have fun, then just go with a bike engine like everyone else has said multiple times. Don't make this harder than it has to be, decide what you are going to do and do your homework.

Nice, you bagged on this newb for asking almost the same question you did just 4 days ago... http://www.diygokarts.com/vb/showthread.php?p=70457#post70457
(and unlike you, he'd already researched how much HP his engine would have!)

Should work out fine there kartmaniac, In a race, It'd probably end up lapping most any of the 6.5 clone powered karts you'll find here on this forum.

 

[kartmaniac]

nice....and it is a 6 speed and its 2-stroke

 

[Gillgamesh64]

Dude the bottom line it what you can afford, and by the sounds of things there is no way you will be building anything yourself soon (just the impression i get) so why dont you tell us all what your budget is and the good people here might be able to give you some good advise!! I had a kart that ran an old 150cc 2stroke when standard it was under 10HP and was a heap of ****

Yo dawg, I herd you liked posting spam to old ass threads...

insane shifter kart?

has anyone used like a kawi zx14 motor or like a cr 500 motor for a shifter kart plz post pics or videos thanks
