  • Boyesen Pro Series Reeds

    Ryan in KS


    cataloguing needs updated as I got these for an 84 atc250r but had to order them for an 85..... same for several years. replaced the ancient metal single stage pedals on this barn find and these really woke the trike up especially in the mid range. seems like it comes onto the pipe a little sooner. no complaints at all.

  • Boyesen Rad Valve

    Dimitri in GA

    Let her breath

    Really woke my bike up. Within the first ride a felt a significant change in the response of the bike. I will say tho the lectron that came on my bike wasn't tuned for it so it was lacking some umph. So I went back to the stock carb and WOW.

  • JD Jetting Jet Kit

    Pasquale in VA

    Noticeable Improvement!

    After years of just dealing with and trying to jet around the dreaded lean bog that plagues the '06 CRF250R, I finally broke down and decided to give this kit a try. All I can say is WOW. Why didn't I buy this kit sooner? The instructions were pretty straight forward, and I installed the suggested needle, main jet, and set the recommended float height (found on their website). Just riding it around the yard, I noticed that it was noticeably easier to start, and it was MUCH more responsive off idle which translated into a much harder hitting feeling off the bottom. I haven't track tested it yet, but I was able to get the bike to bog while it was just on the stand. HOWEVER, I noticed that in order for it to bog, I had to snap the throttle much faster and harder than before. Once I take it to the track, I will be able to verify if the bog has been cured or not. It's not entirely uncommon for the bike to bog on the stand like that, so I'm still hopeful. Also--the kit does address the lean bog issue and includes O-Rings for the AP timing screw. Only complaint I have with this kit is for the money, it should have included some pilot jets. So make sure you have a couple clean pilot jets with you if you order kit PN JDH002. This is why I gave this a 4-star review.
