    Pro X 99101-357 Series Keihin Hex Main Jet

    Donald in AZ

    Simple, cheap, effective

    I picked up about 5 of these to have options due to the low price. May as well bracket my setup so as not to pay multiple shipping fees buying them separately. Turns out I guessed two off and had to go up twice, so this strategy worked out great. Easy in/out, no issues, work as advertised.

    Pro X N424-21 Series Keihin Pilot Jet

    Donald in AZ

    gets the job done

    Needed to go up one pilot and bought a 42. Upon opening up the bottom of the carb the previous owner had already installed a 42. Paid for shipping the second time to get a 45 which works great on this bike with my modifications to the box/pipe/filter. For the price I should have picked up a few the first time to save shipping. I did this with the main, but failed to do it with the pilot. You can buy two of these for the cost of shipping alone so it just makes sense to get more than one. Easy in/out, works flawlessly.

    Great quality and value

    About half the price my local dealer charges! I order everything I can from Rocky Mtn.

  • Pro X Air Filter

    Pro X Air Filter

    Hayden in ID

    Does what it should

    The filter is a nice quality filter and is very durable. I just wish they would be a little more refined to stop the absolute tiny dust from penetrating, but oh well its just as good, if not better, than every other filter I've owned. I run the 'PC Racing' filter skins to keep all dirt from getting in.
