Best tune up I've ever now
The bike was a bear to start cold and didn't have much bottom end punch. After installing the kit it starts better and much nicer to ride with smooth power all the way up.

Good jetting kit but instructions can be vague
I bought this kit because I bought an fmf powercore 4 slip on muffler and knew I would need to re-jet. This kit came with everything I needed. However the instructions aren't very specific for installing but make sense if you have knowledge. I would recommend this for someone else

Good Kit
Kit works as intended but does NOT come with any pilot jets. The main jet numbering system is different than everyone else and makes it hard to compare to the standard jets. Personally after re jetting i would just go to the shop and buy the individual jets. They're about 3 or 4 bucks each. Nothing wrong with this kit and it does work, just disappointed about the pilots jets.

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.

almost complete
It is a good jet kit with the exception it does not contain slow(pilot) jet. Most 4 strokes benefit from bumping this up one size so you don't need to keep the choke on and feathering the throttle for 10 minutes. So check the forums for pilot jet recommendations and don't forget to order a pilot jet.

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!

would have went with JD
this kit works alright, but to me its just a dyno jet set with FMF stickers. I ended up changing out needles and different mains anyhow. this kit also doesn't come with any pilot jets, that would have been nice to know.
