ex250 go kart

[move_out]

hey every one im new to this website at the moment im building a go kart using a Kawasaki 250 motor the problem im having is finding a 520 pitch sprocket to fit on my rear axel if anyone could help it will be much appreciative.

I was wondering the same thing...Can a motorcycle sprocket be made to work on a go cart engine? Is your Kawasaki from a dirt bike? If it is then you should have no problem using a 520 sprocket/chain.

its not from a dirtbike its from a road bike wich uses a 520 chain but most go karts use i think 420

I do believe #50 chain and sprockets are compatible with 520. Get yourself a #50 chain and rear sprocket.

You can buy #520 sprockets here:--> http://www.gokartgalaxy.com/shifter_kart_&_quarter_midget_sprockets_for_3.htm

If you post some pics/measurements of your rear axle style, we could probably recommend a sprocket hub to use with those...

We could probably help you select how many teeth your rear sprocket should be If you post:

Your engines current drive sprocket tooth count, and its redline rpm,
and your rear tires height, and approx weight of the kart/rider(s) ?
and kinda give us more of an idea if the kart will just be for pavement use, or maybe just for serious off-road type riding.

Etcetera, any other info like that would help us to help you out here

I would actually say most go karts use 35, some use 40, but any with a bike style engine uses 420/428/5##, whatever the bike uses.

Those prices on that site for 520 sprockets is high , personally go on Ebay and check there , I found a 520 front , rear and chain in a package deal for a motorcycle on Ebay for $ 59.99 ,alot cheaper .

[Doc Sprocket]

Didn't I see this thing on "1000 Ways To Die"? Whatever you do, don't steer left sharply...

thanks man

 

[anderkart]

the wheels are I think 8"

haha yeap and btw do you think 30tooth on the rear axel would give me good acceleraton plus adecent top speed ?

Racekart slicks like your rears are usually around 11 inches tall, not 8"...

So assuming your rear tires are actually 11" tall, anywhere between a 25 and 30-tooth axle sprocket would be a good choice.

With that engine, I think any tooth combination will give you good speed.

thanks anderkart lol well,i got a 45t on it atm and its poping wheelies lol but it revs out to quickly lol

 

[anderkart]

Yep, you need a smaller axle sprocket, or a larger engine sprocket.

[EvoDre]
