A compact 17mm replacement carburetor by MothAr designed to restore fuel delivery for Honda and compatible 50cc 2-stroke scooters.

It’s an aftermarket unit sized and specified to match common OEM dimensions so it can attach directly to the intake and airbox on compatible years and variants. Before ordering, compare the shape and mounting points of your existing carburetor to the photos to ensure correct fitment.

Which scooter models and years will this carburetor work with?

• Honda Aero 50 (1983–1985) and Aero 50 NB50 (1986–1987)
• Honda Elite 50 variants: SE50 (1988–1990), SE50H/SE50PH (1987), SR (1989–1990), SB50E/SB50P (1988–1989)

• Also compatible with many Kymco/Like and DIO-style 50cc two-stroke scooters

What are the key dimensions and connection details I should check?

Measure your old carburetor and intake components to confirm the MothAr unit will match. Important measurements are listed so you can compare mounting distance and bore sizes directly.

• Throttle bore (intake diameter): 17 mm
• Air filter intake diameter: 28 mm
• Mounting distance (center-to-center): 35 mm
• Compare flange shapes, vacuum ports and throttle linkage before ordering

How does installation and setup typically work?

Installation involves removing the old carburetor, matching the flange and mounting points, and reconnecting fuel, throttle, choke and airbox connections. Professional installation is recommended if you’re not experienced with small-engine fuel systems.

• Drain fuel and disconnect battery before removal for safety
• Install new gaskets or clamps as needed to prevent air leaks
• Adjust idle and air/fuel mixture per factory guidelines after fitment
• Inspect fuel lines and filters while replacing the carburetor

Will this carburetor need tuning or extra parts to work correctly?

Most replacements fit with stock jets and settings but some machines may require a jet swap or idle adjustment to match local altitude and fuel. Inspect the original carburetor’s jet sizes and bring them up to match, or have a mechanic tune the unit for optimal running.

• Possible jet or needle changes for high-altitude or modified engines
• Replace old fuel lines, clamps and filters during the service
• Test idle and throttle response, then fine-tune mixture screw if needed

Who is this for: The MothAr 17mm carburetor is aimed at owners of Honda Elite, Aero and other 50cc two-stroke scooters who need a direct replacement to restore fuel delivery. It’s suitable for DIY mechanics familiar with small-engine work and for shops servicing late-1980s through early-2000s 50cc scooters. Before purchasing, verify your old carburetor’s shape, mounting points and bore sizes against the listed specifications and product photos to ensure compatibility.
