  • JD Jetting Jet Kit

    Great product, would recomend it to anyone!

    Loved JD Jets, I use them in all my bikes and ATVs. The kit comes with all the just you could possibly need when doing a clean/rebuild. The WR250 is known for having a lousy bottom end, this jet kit helped opened it up, along with all the "free mods". To get rid of the low end bog, use this kit and make sure you AP timing is set correctly.

    Its an ok product, I wont buy for myself again

    For the price this is an ok product. I do not think that it suites my need. I did not care for the constructions of the jets. Included with this kit is a "Jet adapter" that converts the carb to accept the FMF jet system. I think that this is a poor design and could only cause more jetting issues later on. The kit did not include a leak jet. I went with JD Jet Kit.
