FAQs

How do you change the gear ratio on a snowmobile? Changing the gear ratio on a snowmobile typically involves replacing the gears in the transmission or chaincase. This is a complex task and should be done by a qualified technician.

What is the formula for calculating gear ratio? Gear Ratio = Number of Teeth on Driven Gear / Number of Teeth on Driving Gear

What gear ratio is best for torque? A lower gear ratio (higher numerical value) is better for torque. For example, a gear ratio of 4.10 is better for torque compared to a gear ratio of 3.73.

How do I find the best gear ratio? The best gear ratio depends on your specific application and goals. For more torque, choose a lower gear ratio, and for more speed, choose a higher gear ratio. Consult your snowmobile’s manufacturer or a specialist for recommendations.

Does a larger gear ratio increase torque or speed? A larger gear ratio (higher numerical value) increases torque and reduces speed.

What is a bad gearing ratio? A bad gearing ratio would be one that doesn’t suit your intended use. For example, if you want speed but have a very low gear ratio, that would be inappropriate.

What ratio should I use for a snowmobile 2-stroke? The ideal gear ratio for a 2-stroke snowmobile depends on factors like engine size, track length, and intended use. Consult your snowmobile’s manual or a mechanic for recommendations.

What is the mix ratio for a 2-stroke snowmobile? Typical mix ratios for 2-stroke snowmobiles are around 40:1, but it can vary. Refer to your snowmobile’s manual for the manufacturer’s recommended mix ratio.

What gear ratio is suitable for performing a wheelie? To perform a wheelie, you’ll typically want a lower gear ratio for better low-end torque. However, be cautious as this can stress the engine and drivetrain.

How do you know the gear ratio without pulling the cover? You can often find the gear ratio listed in your snowmobile’s manual or by checking with the manufacturer. Alternatively, you can count the teeth on the gears if they’re visible without removing the cover.

How do you calculate gear ratio from torque? Gear ratio and torque are related but not directly interchangeable. Gear ratio is determined by the number of teeth on gears, while torque depends on engine power and gearing.

How does gear ratio affect speed? A higher gear ratio (lower numerical value) will increase speed, while a lower gear ratio (higher numerical value) will reduce speed.

Which gear ratio is stronger? There isn’t a direct correlation between gear ratio and strength. The strength of a gear depends on its material and design.

Which gear gives more speed? A higher gear ratio (lower numerical value) provides more speed.

What is the most comfortable gear ratio? The most comfortable gear ratio depends on personal preference and the type of riding you’re doing. It’s subjective and varies from rider to rider.

Which gear will turn the slowest? The gear with the highest numerical value will turn the slowest.

What happens when a small gear drives a larger gear? When a small gear drives a larger gear, it results in a gear reduction. This increases torque and reduces speed.

Do bigger tires raise or lower the gear ratio? Bigger tires effectively lower the gear ratio, which can reduce torque and increase speed.

What are the advantages of a high gearing ratio? A high gearing ratio provides higher top speeds and can improve fuel efficiency. However, it may sacrifice low-end torque.

Is a 90 gearing ratio good? A gear ratio of 90 is extremely high and would likely be impractical for most snowmobiles. It would prioritize speed over torque.

Why is a high gear ratio bad? A very high gear ratio can be bad if it sacrifices too much torque, making it difficult to accelerate or climb steep terrain.

How many miles is too many on a 2-stroke snowmobile? There’s no fixed number of miles that defines when a 2-stroke snowmobile is “too many.” Maintenance and overall condition matter more than mileage.

Is a 4-stroke snowmobile better than a 2-stroke? The choice between a 4-stroke and a 2-stroke snowmobile depends on your preferences and needs. 4-strokes tend to be quieter and more fuel-efficient, while 2-strokes often have more power.

How much horsepower does a 2-stroke snowmobile have? The horsepower of a 2-stroke snowmobile can vary widely, but it can range from approximately 100 to 200+ horsepower for high-performance models.

What is the ideal 2-stroke mix? The ideal 2-stroke oil-to-fuel mix ratio is typically around 40:1, but it can vary depending on the manufacturer’s recommendations.

Will a 2-stroke start with too much oil? Excess oil in the fuel mix can foul spark plugs and affect combustion, making starting difficult. It’s important to use the correct oil-to-fuel ratio.

What is the gas mix ratio for a snowmobile? The gas mix ratio for a snowmobile is typically around 40:1, but always refer to your snowmobile’s manual for the manufacturer’s recommendation.

What is an 8.1 gear ratio good for? An 8.1 gear ratio would be extremely low and suitable for very specific applications that require maximum torque, such as heavy-duty off-road vehicles.

What is a 7.5:1 gear ratio good for? A 7.5:1 gear ratio could be used in various applications, depending on the specific requirements for torque and speed.

What is a 7.3:1 gear ratio used for? A 7.3:1 gear ratio can be used in a range of applications, depending on the desired balance between torque and speed.

How can you tell gear ratio by counting teeth? You can determine the gear ratio by counting the number of teeth on the two gears involved. Divide the number of teeth on the driven gear by the number of teeth on the driving gear to get the gear ratio.

Do gear ratios have to be whole numbers? No, gear ratios don’t have to be whole numbers. They can be expressed as fractions or decimals.

Does the number of gears matter? The number of gears can affect a vehicle’s performance and efficiency. More gears allow for better optimization of power delivery, but it depends on the design and purpose of the vehicle.

What is the gear ratio for dummies? The gear ratio is a numerical representation of how many times one gear spins compared to another gear in a mechanical system.

Is gear ratio directly proportional to torque? Gear ratio is inversely proportional to torque; as the gear ratio increases (numerical value decreases), torque increases.

What happens to speed when you increase torque? Increasing torque typically results in improved acceleration and the ability to overcome resistance, which can lead to increased speed, especially at lower gears.
