shifter kart....

[Kenny_McCormic]

A KT100 has no trans, its a race made motor and needs a special starter, NOT GOOD for a fun cart. Put an add in the paper, get whatever you can used for cheap.

do you know anything bout a yz85 or the yz125? is the yz85 faster than the kt100? thanks

 

[smokin]

is the yz125 motor fit?

 

[modelengineer]

A yz125 should be faster than the kt100 due to the simple fact that it has gears. I don't know enough about kt100's, but I would say that in general an 85cc (or 125cc) engine with 5/6 speed will be faster accelerating AND have a higher top speed than a 100cc engine with only 1 speed.

GET THE YZ125 IT WILL BE PERFECT!

does anyone have a picture on how the cluth and shifter work on the kart? so i know how to connect it when i make it.

My sentiments exactly. A little 85cc kiddie bike engine in a light street kart would be plenty fast for me.

When I was a kid, I bought a homemade go kart built from parts off an old Honda motorcycle, including the engine. I can't remember the CC's, but it was a single cylinder. For that kart, the builder ran some linkage from the original foot shifter up to a lever mounted next to my leg. Then he put the original motorcycle clutch lever on the shifter lever. Instead of shifting down-up-up-up like on a motorcycle, you shifted forward-back-back-back on the shift lever.

BTW, it was geared all wrong. Top end in high gear was like 15 MPH. It could climb a tree, though!! Ugly as sin, too...with the Honda gas tank mounted four feet in the air.

so is a yz85 motor is fast in shifter kart? can i be able to hit 75+mph and lay rubber on the street? if so i'm goin for it.

If you set it up right.

 

[Kenny_McCormic]

No 85cc motor can do both unless you run solid plastic wheels.

 

[smokin]

so with a 85cc cant do wut im lookin for? but anyways wut woule be the topspeed for curiosity? so a 125cc is better?

 

[Kenny_McCormic]

At least a 125 if you want to go 75 AND do a burnout on pavement.

 

[smokin]

were can i find a good 125cc motor and cheap?

 

[crazycart]

Kenny, you would be surprised, i know the KX80's (kawasaki) makes 20 HP.Thats a 80CC! im sure the YZ makes that much too, if its a liquid cooled that is. You can smoke the tires all day long and do 75.

 

[smokin]

im confused! some say a 85cc cant do wut i want and some say it can. so wut is it? yes or no?

Good question. Sounds like none of us has gone down this road before. Let us know what you do.

This would take a bit of fabrication skills to make happen. Is this something you could handle? You may want to consider something more simple...like a souped up Briggs or something.

Can you see the problem with this question?
If you want good, it won't be cheap.
If you want cheap, it won't be good.
I know how cliché that sounds.
The kind of performance you want does not come cheap.
If it did, everyone else would own it....including me.

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.

Ditto
I don't ask...I do.
