22PCS Carburetor Jet Kit w/11 Main and 11 Slow Jets for Nibbi PWK

I purchased this YAMAKATO 22-piece carburetor jet kit to dial in a PWK-style carb, and I’m genuinely impressed with the quality and completeness of the set. What’s included: The kit comes with 11 main jets (100–145) and 11 slow/pilot jets (32–58), which provides a wide tuning range for different elevations, temperatures, and engine setups. This makes it especially useful for anyone running aftermarket carbs or tuning modified engines. Build quality: All jets appear to be well-machined brass, with clean threads and clearly stamped size markings that are easy to read. Threads fit smoothly with no cross-threading or burrs. The pilot jets have clean, evenly drilled orifices, which is critical for consistent idle and low-throttle performance. Performance: After testing multiple jet sizes, throttle response noticeably improved, idle became more stable, and mid-range hesitation was eliminated. The sizing appears accurate, and changes between jets produced predictable, repeatable results—exactly what you want when tuning. Compatibility: Worked perfectly with PWK/Keihin-style carbs and should be compatible with Nibbi, OKO, CVK, and similar designs as listed. Fitment was spot-on with no modifications needed. Value: For the price, this is an excellent alternative to buying individual OEM jets. Having both main and slow jets in one kit saves time, money, and frustration during tuning. Cons: No storage case included, so I recommend organizing the jets in a labeled container to avoid mix-ups. Overall: This is a well-made, thoughtfully sized jet kit that delivers consistent results. Ideal for riders who tune their own carbs and want flexibility without sacrificing quality. I would absolutely purchase this again and recommend it to anyone working with PWK-style carburetors.

Worked great on my XR150L, and now it makes a lot more power. Satisfied.

Bought for my 2023 honda crf150rb. Had no issues installing the 42 pilot jet

Fit and worked just fine. Much cheaper than buying individual Keihin jets. Just wish the kit included larger main jets.

Jet kit includes the right sizes and works perfectly for my carb. Tuning was very easy to do with these jets. Would buy again.

Worked great fits perfectly and gave our bike more power.

There were enough jets to finally find the right one

Did not fit my nibbi carb as advertised.

Beautiful fit and finish

happy with these jets, fit my nibbi carb and got my mini bike running the best it ever has

Fits black & red Nibbi 24mm carb, works as expected

Came as advertised! Was wondering if having a flange on my carburetor would impact anything but so far I've yet to see any hiccups.

Tres bon produit
