⚡ At a Glance
- • Tuning Range: Includes main jets (round and hex) plus TM and VM pilot slow jets to cover common adjustment needs
- • Best for: Motorcycle and ATV owners using Mikuni-style carburettors who need flexible jetting options for tuning
- • Not ideal for: Owners of carburettors outside the listed VM/TM/HSR/RS families or those needing OEM-specific single-size jets
A 42-piece assortment of main and pilot jets tailored for Mikuni-compatible carbs. Designed to help with tuning and replacing worn jets across many VM, TM, HSR and RS series units.
Precise mixture tuning - with a 42-piece selection of main and pilot jets
Main jets determine high-throttle fuel flow while pilot slow jets control idle and part-throttle delivery; changing jet diameters adjusts fuel volume delivered across the rev range.
Enables deliberate richening or leaning of mixtures for modifications, altitude differences or performance tuning without sourcing individual jets.
Broad carburettor compatibility - thanks to explicit VM, TM, HSR and RS model listings
Compatibility includes VM18–VM44, TM24–TM38, HSR42/45/48 and RS34–RS40 families, plus several rack and smoothbore variants; compatible needle jet series are referenced for matching profiles.
Suitable for a wide range of motorcycles, ATVs and off-road machines that use Mikuni-style carburettors, simplifying parts sourcing for workshops and home tuners.
Comprehensive jet variety - with both large round and hex main jets plus TM/VM pilot options
Set contains multiple large round main sizes alongside large hex main sizes, and separate TM and VM pilot slow jets sized for respective carburettor designs.
Provides spare sizes for experimenting and fine-tuning on the bench or on the road, reducing downtime and repeated ordering.
