XIKOBY PZ20 Carburetor & 125cc Starter Kit for 50–125cc ATVs — Complete Ignition & Filter Bundle

XIKOBY’s PZ20 carburetor and 125cc starter kit is a complete replacement set designed to restore reliable starting, improve fuel delivery, and upgrade ignition components for many 50–125cc Chinese-made ATVs and dirt bikes.

This all-in-one kit bundles a PZ20 carburetor with a matched air filter, intake manifold and a full starter/ignition rebuild package — including starter motor, relay, CDI, ignition coil and voltage regulator — so you can replace the most failure-prone parts in a single service session. The components are engineered to fit popular models from Tao Tao, Coolster and a wide range of Chinese manufacturers, aiming to deliver smoother throttle response and steadier starts without hunting for multiple parts.

Will this fit my Tao Tao or Coolster 110cc/125cc ATV?

Compatibility targets many 50–125cc 4-stroke Chinese ATVs and go-karts. The kit is built around the PZ20 carburetor size and includes mounting pieces and gaskets to match common intake configurations on Tao Tao and Coolster models.

• Designed for 50cc–125cc 4-stroke engines that accept PZ20 carburetors
• Lists specific Tao Tao models such as ATA-110 and ATA-125 series and multiple Coolster part numbers
• Includes intake manifold, gaskets and mounting screws to aid fitment

How does the carburetor and ignition bundle improve starting and performance?

The PZ20 carburetor refines air–fuel mixture delivery while the starter and ignition components address weak cranking and erratic spark. Together they can reduce hard-starts and boost throttle responsiveness when installed and tuned correctly.

• PZ20 carburetor improves fuel flow and mixture consistency for steadier running
• Starter motor and solenoid deliver stable crank speed to reduce spin-and-fail starts
• AC CDI and ignition coil provide stronger, more consistent spark energy
• Voltage regulator prevents excess voltage and protects the electrical system

What comes in the box and what tools will I need?

The kit includes the carburetor, intake and consumables plus a starter motor, relay, CDI box, ignition coil, regulator, spark plug and assorted gaskets, hoses and clamps. Basic hand tools and some mechanical knowledge are sufficient for most DIY installs, though a service manual helps with tuning and torque specs.

• Included: PZ20 carburetor, air filter, intake manifold, CDI, starter motor, solenoid, coil, regulator, spark plug
• Also supplied: rubber fuel lines, fuel filters, clips, screws, gaskets and O-rings
• Recommended tools: metric sockets/wrenches, screwdrivers, pliers, basic feeler gauges and carburetor cleaner

How do I maintain or tune the new carburetor and ignition parts?

Initial tuning typically focuses on idle mixture and main jet selection to match your altitude and riding style; the CDI and coil require no tuning but should be secured and grounded correctly. Regular inspection of fuel lines, filters and fasteners will help keep the system reliable.

• Set idle and mixture screws per factory guidance, then fine-tune with a plug chop or plug inspection
• Check fuel lines and filters regularly for clogs or leaks
• Ensure electrical connections are clean, tight and protected from moisture

Who this is for: This kit is aimed at owners of Tao Tao, Coolster and similar Chinese-brand 50–125cc ATVs, pit bikes and go-karts who need a cost-effective way to replace worn fuel and starting components in a single purchase. It suits home mechanics who prefer a consolidated rebuild package and enthusiasts wanting improved starting reliability and crisper throttle response without sourcing individual parts.
