The majority are from 3000 to 4000 RPM. Enter the number of teeth or sprocket splines on the axle (higher number, probably 50 to 70) and on the clutch or engine (smaller number, probably 8 to 15). The ratio of those numbers yields the best power (faster acceleration) or the best high end speed, or a compromise of both.
Will a smaller sprocket make my go-kart faster?
You may find this counter-intuitive, but to go faster, the final drive sprocket needs to be smaller, not bigger. Conversely, to go faster, the clutch sprocket needs to be bigger. So, a simple way to change your gearing is to have one or more extra primary drive sprockets and/or final drive sprockets.
How do you find the gear ratio on a go-kart?
To determine your gear ratio, simply divide the rear axle sprocket by the clutch sprocket, so in the case of the above example, 60 divided by 12.
What is the best clutch for a go-kart?
The MoonSun clutch is the best go-kart clutch in our list, as it offers the perfect ratio of build quality and affordability. It’s a great clutch for Briggs and Stratton, Tecumseh, Predator and other small to medium go-kart engines. This centrifugal clutch has a height of 55mm (2.17”) and a diameter of 107mm ( 4.21”).
How do I choose gear ratios?
The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.
How fast can a 13 hp engine go?
This is a utility vehicle not a racer so top speed is about 15 mph.
How do I increase my go kart speed?
Here are 9 ways to make your go-kart faster:

- Optimize Your Carburetor.
- Install a Supercharger or Turbocharger.
- Re-gear Your Go-Kart.
- Make Your Go-Kart More Lightweight.
- Remove the Speed Governor.
- Change to Larger Go-Kart Tires.
- Add Isopropyl Alcohol to Your Fuel.
How fast does my go kart go?
Most karts max out around 40-50mph, while this is a maintained speed that is safe and as controlled as you can be. It’s a speed that is comfortable in the sense of you wont fly off the track, and hurt other racers or patrons. At LVGP ours max out at around 45mph.
How fast is a 420cc go kart?
The predator engine has a 40 series Torque Converter. The top speed was 33 mph.
How fast does a 208cc go kart go?
HIGHLIGHTS: 208cc 4-Stroke engine with 3 year warranty. Power & Speed: cruise up to 24 mph.
Do you need a clutch for a go kart?
The purpose of a clutch is to disengage and engage the engine from the load it is pulling. The necessity of disengaging the clutch is equally important for safety as it is for performance. Gas engines in particular all the time and need to be disengaged when the gokart is being stopped or slowed down.
Is a torque converter better than a clutch?
Torque converters are great for lower end torque, as they have the ability to adjust the gear ratio depending on the engine’s RPM. … On the other hand, a regular clutch maintains the same gear ratio all the time. This makes it more suitable for lightweight or racing go-karts that are tuned for maximum speed.
What gear should I use going uphill?
While going uphill, use the D1, D2, or D3 gears to maintain higher RPMs and give your vehicle more climbing power and speed. Note: Most automatic vehicles have at least a D1 and D2 gear, while some models also have a D3 gear.
What is a good gear ratio for highway driving?
For on-highway linehaul, the range tightens to a fuel friendly 2.26 through 3.42 for the most common ratios. “For on-highway, direct drive, it starts all the way down at 2.26 and up to 3.08 or larger,” Garrison says.
What is the best gear ratio for speed?
In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.
