Chinese High Performance Scooter Parts

Compatible Brands

The performance parts in this catalog are designed for GY6-based scooters and mopeds. They are compatible with all major Chinese GY6 brands in U.S. circulation:

Always confirm engine displacement before ordering. GY6 50cc and 150cc engines share the same external architecture but differ in bore diameter, carburetor jetting, and some variator specifications. Parts listed for 150cc are not compatible with 50cc without modification.

Performance Upgrade Kits

A complete GY6 performance upgrade kit for 50cc or 150cc scooters is the fastest way to make a meaningful improvement across multiple areas in a single order.  Complete kits typically include a high-flow air filter, performance exhaust, upgraded variator with lighter roller weights, and higher cc cylinder and head.  Buying matched components together eliminates the tuning uncertainty that comes from mixing upgrades sourced from different suppliers, and it gives the engine a balanced configuration out of the box.

We stock upgrade kits for both 50cc and 150cc GY6 platforms, clearly labeled by displacement.

Variators and Roller Weights

The variator is the single most impactful performance upgrade on a GY6 scooter for everyday riding. The stock variator uses roller weights that are often heavier than ideal, which delays the shift to a higher drive ratio and limits how quickly the engine reaches its power band. Replacing the rollers with a set matched to the specific engine's output curve — lighter weights for more responsive acceleration, heavier for stronger top speed — transforms how the scooter responds off the line and through the mid-range.

Performance variator kits include a billet aluminum variator face, roller weights in multiple weight options, and a performance contra spring. We stock kits sized for GY6 50cc and 150cc separately.

Performance CVT Belts

A performance CVT belt uses a harder, more heat-resistant rubber compound that reduces slip under load and extends the service interval. Belt width and outside circumference must be confirmed before ordering. GY6 50cc and 150cc belts use different dimensions and are not interchangeable.

High-Flow Air Filters

Swapping to a high-flow air filter on a Chinese 150cc scooter increases airflow to the engine above what the stock foam element can deliver. upgrade increases airflow to the engine above what the stock foam element can deliver. Increased airflow alone on a stock-jetted engine will lean the air-fuel mixture, so a high-flow air filter should always be paired with a main jet upgrade to maintain the correct fuel delivery. We stock high-flow filter assemblies for GY6 150cc carburetors and the adapter hardware needed to fit them to the standard airbox inlet.

Performance Exhaust Systems

A performance exhaust reduces back-pressure and improves power in the upper RPM range. Most GY6 performance exhausts are direct-fit replacements with no modification required. The gain is most noticeable when combined with a high-flow air filter and a re-jet.

We stock complete performance exhaust systems for GY6 50cc & 150cc scooters with header diameter and mounting flange confirmed for GY6 fitment.

Performance Carburetors and Jet Kits

The stock GY6 carburetor is calibrated for emissions compliance and becomes a limiting factor once other upgrades are in place. A performance carburetor with a larger venturi diameter improves throttle response on a modified engine. Jet kits are the recommended first step when re-jetting for an air filter or exhaust upgrade.

Racing Clutch Systems

A high-performance racing clutch for your scooter replaces the stock driven pulley assembly with a unit designed for higher engine speeds and sharper engagement characteristics. Racing clutch assemblies use a higher-tension spring that delays engagement to a higher RPM, allowing the engine to reach its power band before the drivetrain loads up. The result is faster acceleration from a standing start and a more aggressive feel through the mid-range. Racing clutch kits for GY6 150cc scooters are a direct-fit replacement for the stock driven pulley and require no frame modification.

Performance CDI and Ignition

Upgrading to a performance CDI and ignition coil on a GY6 scooter removes the RPM limiter built into the stock unit and advances ignition timing for improved combustion efficiency at higher engine speeds. upgrade removes the RPM limiter built into the stock CDI and advances ignition timing for improved combustion efficiency at higher engine speeds. The stock GY6 CDI limits engine speed to approximately 7,500 to 8,000 RPM to meet emissions and longevity targets. A performance CDI raises this limit and optimizes timing across the RPM range, allowing the engine to reach and sustain higher speeds. The performance ignition coil is matched to the CDI's higher output requirements and produces a stronger, more consistent spark.

Always confirm AC or DC ignition type before ordering. GY6 scooters may use either type depending on brand and model year, and AC and DC CDI units are not interchangeable.

Big Bore Kits

A big bore kit brings a GY6 150cc to 180cc. It is the most involved, as it requires the cylinder and head.

Why Buy From Get 2 It Sales

We stock performance parts for Chinese GY6 scooters and back every order with genuine product knowledge:

• Every incoming shipment is physically inspected before it enters our inventory
• Parts are cataloged by displacement and confirmed fitment, not generic compatibility claims
• Nearly 100 years of combined team experience in Chinese powersports
• Free shipping on orders over $100 to the continental USA
• Dealer program available for repair shops and resellers
• Technical support for upgrade selection and fitment questions

Performance parts for Chinese scooters require verified sourcing. A variator listed as GY6-compatible may not fit the specific crankshaft taper on your engine. Our inspection process verifies that parts match their stated specifications, and our team can advise on compatibility and installation order.

Frequently Asked Questions

Will performance parts void my scooter's warranty?

Most Chinese scooters sold in the U.S. consumer market have limited warranties that do not cover modifications. If your machine is still under warranty, check the terms before installing performance parts. For machines outside the warranty period, performance upgrades are straightforward to install and reverse if needed.

Do I need to re-jet after adding a high-flow air filter?

Yes. A high-flow air filter increases airflow to the carburetor, which leans the air-fuel mixture. Running lean without re-jetting causes overheating and can damage the engine over time. We stock main jets in multiple sizes for the GY6 carburetor.

What is the difference between a racing clutch and a standard clutch on a GY6 scooter?

The standard GY6 clutch engages at a relatively low RPM, which keeps the engine below its power band during initial acceleration. A racing clutch uses a stiffer spring that delays engagement to a higher RPM, allowing the engine to build speed before the drivetrain loads up. The result is faster acceleration but a slightly more abrupt feel at low speeds.

What is your shipping policy?

Free shipping on orders over $100 to the continental USA. Oversized and overweight items are excluded and subject to separate rates. Parts ordered by 1:00 PM EST are shipped the same day.

Can I speak with someone about which upgrades are right for my scooter?

Yes. Our team is available Monday through Friday, 8:30 AM to 4 PM Eastern. Call us at (864) 595-9930 or reach out through our contact page at get2itparts.com/pages/contact-us.

Do you stock individual components or only complete kits?

Both. We stock complete performance upgrade kits as well as individual components including roller weights, belts, jets, filters, CDIs, and exhaust systems. Riders who want to upgrade in stages or replace a single worn performance component can order individual parts without purchasing a full kit.
