[Kartbuilding] need some information

[Stephen Burke]

Hi,

Having a single transmission (i.e. no gears) will be fine. I suggest you 
get a good centrifugal clutch which will allow you to stop the kart and 
keep the engine going. (see: 
http://blog.kartbuilding.net/2007/06/26/using-a-centrifugal-clutch-and-chain-drive/ 
)

As you are going for a two-seater, you will need a good size engine.

The material used for go-kart frames is typically 1" or 1.5" (25 - 35mm) 
diameter mild steel tube. I recommend you go with 1.5" (35mm) steel tubing 
for a two-seater kart.

As for suspension, things can get tricky here. Would it be possible to 
build the kart without suspension, and afterwards adapt it to add in the 
suspension? It's just an idea, and it will mean that you can get the kart 
made quicker.

Take a look at youtube, as there are some good videos showing making a 
kart with suspension.

Best of luck,
-steve
