    Just as good as OEM!

    I always buy Pro X jets when I rejet my bikes. There the same as OEM in my opinion and are cheaper!

    Works great

    Made a big difference in throttle response and no more lagging at mid throttle. Well worth the money.

    Beta 300 RR - Runs so much better with JD Jet Kit

    I'm the type that thought, hmmm, I can just buy some jets and try myself instead of spending money on a jet kit. After reading the reviews, I broke down and bought the JD Jet Kit for my 2017 Beta 300 RR, which was running super rich from the factory. After installing the kit, which was super easy, the bike runs much much better, doesn't have the hesitation it did, and doesn't spew oil out the tail pipe. I'm extremely pleased that I broke down and bought this kit. Do yourself a favor... buy the kit that has all the research done for you and save yourself time and headaches.

    Nothing beats the real deal

    I prefer the name-brand jets, not because I've had issues with others (like pro-x) except that the sizes don't always match up with the OEM jets. These jets are the best choice.
