[Kartbuilding] Fwd: Doubts on the kart

[Stephen Burke]

Hi Navin,

1st - No you should not install a hand operated clutch lever. A clutch
requires a lot of effort to be operated correctly. Also - apart from
the difficulty, it will require too small (precision) a movement to
operate correctly. It is best to have 3 pedals - one for the clutch,
one for the brake and one for the accelerator - and in the same
arrangement as in a car. It also gives the driver a better universal
experience when driving a car. So young people can learn to drive a
car - in this kart - i.e. they are getting used to the clutch -
accelerator relationship.

The end of the steering column. There is a picture attached to this
email showing the end of the steering column.
I suggest you go to this page:
http://www.skynet.ie/~steviewdr/racingkart/edrawing/index.html
and download the executable edrawing and zoom/ rotate the kart.

The bearings in the rear axle have special holders with bolt holes.
This allows you to bolt the holder directly to the kart. These can be
purchased directly from an engineering shop.

There are details and pictures on my website for the brake and sprocket.
Bottom of this page
http://www.skynet.ie/~steviewdr/Freeplans/brakeandsprocket.htm
I made the above holders. Get some diameter 100mm steel bar. part off
a 25mm piece.
Take down one side to a diameter to suit the internal diameter of
sprocket/ brake.
Drill hole thro. for axle.
Weld all.

My brakes are wire operated. On the above page - both methods are outlined.

Your engine will do fine. It would be better if it was a 2 stroke -
but sure you have to make do.

You can keep in touch with me for questions/ suggestions - IF YOU ONLY
GO THROUGH MY WEBSITE COMPELTELY.
All of the questions you asked are already covered on my website.

My kart does approx 45-50 mph.

15 teeth on sprocket for teh engine.
45 teeth on the rear axle.

Best of Luck
-steve
