In reply to Jason K.. @Jason: well If the Hillard clutch with #35 sprocket is rated for 13hp, then it should be ok. I've rarely seen chains break on tensile strength. It may wear the sprocket teeth quite quick. Let us know how it goes for you.

In reply to Steve c.

@Steve: 10 tooth on clutch and 48 on rear gives a gear ratio of 4.8:1
This wouldn’t be suited to going up hills. You would want a ratio of 6:1 or greater.
It also depends on how big your rear wheels are. If you have big rear wheels – then you need a bigger ratio.

I suggest you try and get a larger sprocket for your rear axle.

You could also try and setup a “transfer axle”, where you use a “middle shaft” and use two chains in order to get a good ratio.

Hello. I have just recently bought a go kart that has a new 11hp motor on it. The torque convertor on the motor I believe was only rated for 8hp and chewed the belt like nothing. So I just bought a Hillard clutch that is rated for 13hp and has 17 teeth. My tires are 22 inch. Now I just ordered a 85 tooth axel sprocket to give me a 5:1 ratio. My only concern is that the Hillard clutch has a #35 chain, so will the new sprocket. Do you think that #35 chain is good enough. I weigh 250lb and I know the go kart is about that much in weight.

hi, i’m building a go kart with the n shaped yoke attached to the chassis and the king pin bolted in the n shaped yoke and free to move about the bolt. the stub axle and track rods are welded on the king pin with an angle of 104 degrees between the stub axle and track rod. their is no suspension to the kart. is it still important to consider the castor, camber and ackermann angle?

Hi I am thinking of taking a Yamaha zuma X50 scooter that has a automatic dry centrifugal clutch and a CVT as common on these scooters. I want to cut off and remove the CVT transmission and put up a conventional GoKart centrifugal clutch on the drive shaft of the engine. Is this possible? I am doing this for the Shell Eco Marathon project. Your early reply is highly appreciated.
