The ideal gear ratio for a 6.5 HP go-kart engine typically falls between 5:1 and 8:1, depending on the track type and intended use. A lower ratio (closer to 5:1) provides better acceleration and is suitable for flat tracks, while a higher ratio (closer to 8:1) can enhance top speed on longer, straight tracks. It's essential to consider factors like tire size and weight of the kart when selecting the optimal gear ratio. Testing different ratios can help fine-tune performance for specific racing conditions.

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
For a sixth-mile dirt track in an open class kart racing setup, you'll typically want to use a gear ratio that balances acceleration and top speed. A common recommendation is to start with a gear ratio around 4.5:1 to 5:1, but this can vary based on your engine's power band and track conditions. It's essential to test different gears during practice sessions to find the optimal setup for your specific kart and driving style. Always consider factors like track surface, tire grip, and weather conditions when making your final gearing choice.
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.
Yes , you need a gear box to make it work.
To keep the cost down they use a centrifugal clutch off the engine.
The speed of a 7 hp go-kart engine can vary based on several factors, including the weight of the go-kart, the gearing ratio, and the type of terrain. Generally, a 7 hp engine can propel a go-kart to speeds between 30 to 50 mph (48 to 80 km/h) under optimal conditions. To get a more accurate estimate, the specific gearing and weight of the go-kart would need to be considered.
You cannot gear something for both, you should be able to find a ratio that makes you happy. If you gear it for low end or fast take-off, you will lose tope end. If you gear it for top end you will lose the low end. There are alot of variable you did not mention, engine size, and performance mods. If you want it to have faster top end than it does now, decrease the size of the sproket on the drive axle or increase the sproket on the motor. I would not do both at once, change one or the other. Go to you local go-cart shop they should be able to help.
To remove a limiter from a go-kart, first ensure safety by disconnecting the battery and wearing appropriate protective gear. Locate the limiter, which is usually part of the engine's wiring or the carburetor's throttle linkage. Carefully disconnect or modify the limiter according to your kart's model, but be cautious as this can affect performance and safety. Always consult your go-kart's manual and local regulations regarding modifications before proceeding.
