My Buying Guides on ‘Gy6 200Cc Big Bore Kit’

If you’re looking to increase the power and performance of your Gy6-powered scooter, a 200cc big bore kit is a great option. A big bore kit replaces the stock cylinder and piston with larger components, which increases the engine’s displacement and produces more power.

There are a few things to consider when choosing a 200cc big bore kit for your Gy6 scooter. In this buying guide, I’ll discuss the different factors you need to take into account, as well as recommend some of the best kits on the market.

Factors to Consider When Choosing a 200cc Big Bore Kit

  • Displacement: The displacement of a big bore kit is measured in cubic centimeters (cc). The larger the displacement, the more power the kit will produce. However, it’s important to choose a kit that is compatible with your scooter’s engine.
  • Compression ratio: The compression ratio of a big bore kit is the ratio of the volume of the cylinder when the piston is at the bottom of its stroke to the volume of the cylinder when the piston is at the top of its stroke. A higher compression ratio produces more power, but it also requires higher-octane fuel.
  • Camshaft: The camshaft in a big bore kit controls the timing of the valves. A different camshaft can be used to improve performance, but it’s important to choose one that is compatible with your scooter’s engine.
  • Head gasket: The head gasket seals the combustion chamber between the cylinder head and the cylinder. A high-quality head gasket is essential for preventing leaks and ensuring proper engine performance.
  • Other components: In addition to the cylinder and piston, a big bore kit typically includes other components such as a crankshaft, connecting rod, and valves. It’s important to make sure that all of the components in the kit are compatible with each other and your scooter’s engine.

Recommended 200cc Big Bore Kits for Gy6 Scooters

  • Stage 1: If you’re looking for a simple and affordable way to increase the power of your Gy6 scooter, a Stage 1 big bore kit is a good option. These kits typically include a cylinder and piston that are 200cc, a new head gasket, and a high-flow air filter.
  • Stage 2: A Stage 2 big bore kit is a good option for riders who want more power and performance than a Stage 1 kit can provide. These kits typically include a higher-compression cylinder and piston, a different camshaft, and a high-performance exhaust system.
  • Stage 3: A Stage 3 big bore kit is the most powerful option available. These kits typically include a large-displacement cylinder and piston, a high-compression head, a performance camshaft, and a full exhaust system.

A 200cc big bore kit is a great way to increase the power and performance of your Gy6 scooter. By considering the factors listed in this buying guide, you can choose a kit that is compatible with your scooter and meets your performance goals.
