A 500cc horizontal-shaft engine is the closest match here for buyers replacing or building around a large-displacement go-kart powerplant. The DuroMax XP20HPE is best for buyers who want electric and recoil starting, while the XP20HP offers recoil starting. The other listings are a starter motor, a 500cc engine repair assembly, and a smaller 212cc engine—not complete 500cc replacements.
| Product | Best For | What It Is |
|---|---|---|
| DuroMax XP20HPE | Electric and recoil starting | 500cc engine |
| DuroMax XP20HP | Recoil starting | 500cc engine |
| Linhai 500cc starter motor | Replacing a compatible starter | Starter component |
| 212cc 7.5 HP engine | Buyers considering a smaller engine | Complete engine |
| HS500 cylinder assembly | Repairing a compatible 500cc engine | Engine component |
DuroMax XP20HPE 500cc Engine
The DuroMax XP20HPE is a 500cc, four-stroke OHV, horizontal-shaft gas engine. Its listed features include recoil and electric starting, a 1.35-gallon fuel tank, and operation on standard 87-octane gasoline.
Best for: Buyers who want both electric and recoil starting in a 500cc engine. It is the strongest fit in this selection for shoppers seeking a complete engine at the listed displacement.
Check before buying: Confirm that the engine’s shaft dimensions, mounting arrangement, and other specifications suit the intended kart. The provided product details do not establish compatibility with a particular frame or drivetrain.
DuroMax XP20HP 500cc Engine
The XP20HP is also listed as a 500cc, four-stroke OHV, horizontal-shaft gas engine. It has recoil starting, a 1.35-gallon fuel tank, and uses standard 87-octane gasoline.
Best for: Buyers seeking a 500cc DuroMax engine who are comfortable with recoil starting. Compared with the XP20HPE, its listed starting method is simpler: recoil rather than electric and recoil.
Check before buying: Recoil starting may not suit buyers who specifically need electric starting. As with any engine swap, verify mounting and shaft details against the kart before ordering.
Linhai 500cc ATV Starter Motor
This listing is for a starter motor, not a complete go-kart engine. The product name identifies it as a starter for Linhai 500cc ATV and related BMS Motor Sports Eagle and Woodsman 500XL applications. Its feature description highlights quick starting, stable operation, durability, and quiet operation.
Best for: Owners repairing a listed compatible application who need a starter component. It is included because it relates to a 500cc engine, but it is not a replacement for the engine itself.
Check before buying: Confirm the existing engine and starter-part fitment carefully. The listing details provided do not establish universal compatibility with 500cc go-karts.
212cc 7.5 HP Go-Kart Engine
This is a complete, pull-start, single-cylinder, four-stroke engine rated at 212cc and 7.5 horsepower, so it is not a 500cc alternative. The listing gives a 20mm crankshaft diameter, 50mm crankshaft length, 0.8-gallon fuel tank, and 3,600 rpm.
Best for: Buyers comparing a smaller engine option for a go-kart or other listed equipment. Its stated shaft measurements make it especially important to compare the kart’s existing requirements before purchase.
Check before buying: The product notes say the crankshaft is slightly larger than a standard 3/4-inch size. They also advise checking oil level if the engine will not start.
HS500 Cylinder Assembly And Piston Rings
This listing is an engine repair component set, not a complete 500cc engine. It describes a cylinder assembly, piston, and rings designed for 500cc HS500 ATV and UTV engine models. The stated purpose is to support compression and throttle response, with high-grade steel construction described for off-road use.
Best for: Buyers repairing a compatible HS500 engine who need the listed cylinder and piston components. It is relevant to 500cc engine maintenance, rather than a go-kart engine replacement.
Check before buying: The listing specifies HS500 applications. Verify the exact engine model and required parts; the description does not indicate universal fitment.
Buying Guide: How To Choose A 500cc Go-Kart Engine
Do you need a complete engine or a replacement part?
Start by identifying the job. The XP20HPE and XP20HP are listed as complete 500cc engines. The starter motor and HS500 cylinder assembly are components for repairs, while the 212cc listing is a complete engine at a different displacement. A part will not replace an entire engine.
Which starting system should you choose?
Choose the XP20HPE if electric and recoil starting are both priorities. Choose the XP20HP if recoil starting meets your needs. The provided details do not specify starting features for the other products beyond the 212cc engine’s pull start.
What dimensions should you verify?
Compare shaft diameter and length, mounting points, and drivetrain requirements with the kart’s specifications before ordering. The 212cc listing supplies crankshaft measurements; the provided details for the DuroMax engines do not give equivalent measurements. Do not assume that matching displacement alone guarantees a fit.
What fuel and operating details matter?
The two DuroMax engines are listed for standard 87-octane gasoline and have 1.35-gallon tanks. The 212cc engine has a listed 0.8-gallon tank. Follow the chosen engine’s own operating and maintenance instructions, and confirm that its requirements suit the intended setup.
Frequently Asked Questions
Which product listed is a complete 500cc engine?
The DuroMax XP20HPE and XP20HP are both listed as complete 500cc engines. The starter motor and HS500 cylinder assembly are parts, not complete engines.
What is the difference between the two DuroMax engines?
The XP20HPE is listed with electric and recoil starting. The XP20HP is listed with recoil starting. Both are described as 500cc, four-stroke OHV engines with 1.35-gallon tanks.
Is the 212cc engine a 500cc replacement?
No. It is a 212cc engine, a substantially different listed displacement. Check the kart’s requirements before considering it as an alternative.
Does a 500cc engine automatically fit a go-kart?
No. Displacement alone does not establish fit. Verify shaft dimensions, mounting arrangement, and drivetrain requirements for the specific kart.
Can the HS500 cylinder assembly replace a complete engine?
No. It is a set of engine components described for compatible HS500 ATV and UTV models. Confirm the engine model and repair requirements before selecting it.
