The Yamaha PW50 Jet Assortment

Because finding individual jets for a PW shouldn't be a part-time job.

Stop scouring obscure forums and waiting on backordered single parts. If you’ve ever tried to tune a Yamaha PW50, you know the struggle: the jets are tiny, specific, and seemingly always out of stock when you actually need them.

We’ve put together this Assorted Jet Selection specifically for the dads, mechanics, and track-side heroes who want to stop guessing and start riding. This isn't a complex "rebuild kit" with parts you don't need—it’s a curated stash of the most essential brass for your toolbox.

What’s in the Box?

Everything you need to lean it out for the heat or richen it up for the cold. You get a total of 8 factory-spec jets:

4 Pilot Jets

• #35, #37.5, #42.5, #45
• Perfect for fixing those stubborn idling issues and crisping up off-idle throttle response.

4 Main Jets

• #62.5, #65, #72.5, #75
• Essential for dialing in top-end performance regardless of your elevation or oil ratio.

Why You Need This:

• One-Click Convenience: No more adding eight different items to your cart from three different vendors. It’s one part number, one package.
• Toolbox Insurance: Elevation changes? New exhaust? Sudden cold snap? You’ll already have the leaner and richer options on hand to keep the little 50 screaming.
• Factory Fit: Designed specifically for the PW50 carburetor to ensure you aren't fighting stripped threads or poor atomization.
• Note: This is an assortment of jets, not a tuning "kit." It’s designed to give you options and spares so you’re never the dad at the track asking if anyone has a spare #65 main.
