These fit the bill if you're looking for a good set of basic jets for smaller engines. I've used two different sizes from the set and noticed that every single one of them is very well machined and nicely made.The brass is shiny, no corrosion and no blemishes or other defects. Inexpensive, accurate and useful. Nothing wrong with that!

Jets look nice, but are no where near correct sizes as labeled. Don’t buy these unless you want to guess what size jet you are installing….

These jets from Keihin OKO KOSO helped breathe new life into my engine with their variety of options for fine-tuning the fuel mixture. They arrived promptly and were well-packaged, which I appreciated.

I purchased this slow pilot jet for my motorcycle, and I’m very impressed with the quality. It fit perfectly into my carburetor and resolved the idling issues I was experiencing. The jet seems well-made and durable. Installation was straightforward, and I noticed an immediate improvement in performance. If you’re dealing with a rough idle or cold starts, this is a solid replacement part. Highly recommended!

Unbeatable deal, 40 Jets for the price of one genuine one. I use this jet kit to tune my mini bikes that don't run right at higher elevation. It easy to lean the fuel mixture with this assortment . Received on time too. Don't worry about quality because the jet I needed was.
