a gear-box kart i think it can do about a 150 mph depending on how you gear it
It depends on: * how much it weighs, * what it's bhp (brake horsepower) is, * how aerodynamic it is, * the gear ratio between the engine and drive wheel(s).
anywhere from 35 mph to 110 depending on the gear ratio and the horsepower and the max rpm of the engine
The clutch of a go kart is much the same as the clutch on a car. The clutch disengages the engine from the gearbox enabling the gear to be changed. Without a clutch gear changing would be difficult and may damage the gearbox.
In some 1982 Ford f100 trucks I know they have a 4.10 Gear ratio like my truck but with that gear ratio if you go over 55 mph you can say goodbye to your gas mileage so get a smaller gear ratio.
It depends on what you need - if you want lots of speed no power on the bottom end you go with the high ratio - if you want lots of torque on take off and lots of pulling power you take the low gear ratio.
Yes , you need a gear box to make it work.
It would depend on the gear ratio.
Horse power and gear ratio.
It should go from 30 to 40 mph depending on your gear ratio
improve as in go quicker or higher speed? for a lower gear ratio to go better up hills go to a lower gear ratio like 4 to 1. For a faster highway speed and better fuel milage go to a higher ratio like 2.7 to 1. The gears in both axles, front and rear must be changed to improve the ratio.
Pick a gear that gives you the right ratio, then go for it. No difference than from a single-speed bike.
