  • Nihilo Concepts Jet Kit

    Quick and crisp

    The Nihilo kit is very good. Throttle response is more crisp and has leaned the bike to a very nice plug color. Very happy with kit.

    Really wakes the bike up!

    I installed these with a pure Polaris exhaust and a K/N air filter with a forced air induction system I built on it and they do a great job keeping up with all the extra air flow and not letting the bike run lean. very happy with the kit. I put in the 175 main and a 45 pilot. (Kit does not include pilot jet) I have installed this kit on 3 of our quads now and they all run great!

    Woke up the bike

    I was having serious cold start issues on my girlfriends bike. Between this and a K&N air filter it starts up fine on about the third kick from cold. It would get 5 stars if it started first kick when cold. It is important to note I rebuilt the carb on this bike with this jet kick after the bike sat for several years when the P.O owned it. So maybe all the bike needs is some more hours on it. But once the bike has been ran it starts quick every time and has added a few ponies over stock. Much more enjoyable to ride, and no more stalling makes her much more confident in her machine and allows her to push her self knowing the bike won't be the problem.

    Well worth the $

    Excellent product. It would be nice if it were possible to only purchase the needle. Either way, my crf450x runs great now.
