YGQ Carburetor Pilot Slow Jet Kit for Mikuni VM/TM Carburetors VM22/210 — Full 10–50 Jet Assortment for Idle & Low-Throttle Tuning

YGQ Carburetor Pilot Slow Jet Kit for Mikuni VM TM Carburetors VM22/210 provides a complete set of pilot/slow jets in multiple sizes to fine-tune idle and low-throttle fuel delivery on compatible Mikuni and similar carburetors.

This pilot/slow jet kit from YGQ includes a wide range of jet sizes (10 through 50 in 2.5 increments) designed to fit many Mikuni VM and TM series carburetors and equivalent aftermarket models. Whether you're re-jetting for altitude, tuning for a different exhaust or intake, or replacing worn jets, this assortment gives you matched increments so you can dial in throttle response and idle mixture precisely. The kit lists compatibility across VM18 to VM44, TM24 to TM38, and several round- and flat-slide variations — check the fit notes for your specific model before buying.

Which Mikuni carburetors does this kit fit?

The YGQ kit covers a wide selection of Mikuni VM and TM series carburetors plus many early TMS/TMX and non‑OEM versions. It is compatible with flange-mounted and spigot-mounted variants, and includes jets suitable for round- and flat-slide models. Always cross-reference your carburetor model number with the kit’s compatibility list.

• Fits VM18, VM22, VM24, VM26, VM28, VM30, VM32, VM34, VM36, VM38, VM44 series where pilot jets are used
• Compatible with TM24–TM38 flat and round slide types (excluding units with accelerator pump)
• Covers many OEM and aftermarket Mikuni-style carburetors and early TMX/TMS models

How do I choose the right jet size for my tuning needs?

Select a jet by starting at the factory-recommended pilot size, then move up or down in small increments to compensate for changes. Leaner conditions (higher altitude, freer-flowing exhaust) usually require larger pilot jets; richer conditions (denser air, restrictive intake) often need smaller jets. Try one size change at a time and test at idle and part-throttle to assess results.

• Begin with stock jet size as a baseline
• Adjust in 2.5-size steps included in the kit for controlled tuning
• Test idle, transition off-idle, and low-throttle response after each change

What sizes are included and how are they packaged?

The kit supplies pilot/slow jets in sizes from 10 up to 50 in 2.5 increments, covering most common tuning needs. Jets are typically small brass components, individually numbered, and supplied so you can pick specific sizes without buying single jets. Inspect the product images and size chart before ordering to ensure you select the correct variation or full set.

• Size range: 10, 12.5, 15, 17.5 ... up to 50 (2.5 increments)
• Individual, numbered jets for easy selection and replacement
• Clear size labeling recommended—verify with pictured size chart

Can I use these jets for both 2-stroke and 4-stroke applications?

Yes — the kit is suitable for many OEM 2-stroke and 4-stroke carburetors that accept Mikuni-style pilot jets. Performance characteristics differ between engine types, so use the jets as part of a careful tuning process specific to your engine. Avoid guessing: check your carburetor model and test progressively to find the correct mixture.

• Intended for a broad range of 2-stroke and 4-stroke Mikuni-style carburetors
• Useful for altitude compensation, aftermarket exhaust/intake tuning, and wear replacement
• Not intended for carburetors with built-in accelerator pumps or unspecified non-compatible designs

Who is this for: Riders, mechanics, and DIY tuners who work on motorcycles, ATVs, go-karts, and small engines using Mikuni VM/TM family carburetors or compatible aftermarket units. This kit suits anyone who needs precise control over idle and low-throttle fueling — from hobbyists performing routine maintenance to experienced tuners optimizing engine response. Always confirm carburetor compatibility and start tuning with incremental changes for the best results.
