Great Tune Up
Bike sounds and runs way better after switching out the jets. No idea how if the power is better, but I'm definitely of fan of how it feels now.

Eleminate the bog on XR650L
After installing the FMF Power-Up Jet Kit the XR650 preformed great, the low end throttle bog is gone and much better performance overall!

Awesome upgrade!
Something so simple as proper jetting completely changed the way response and power output of this 2005 Blaster 200 2 stroke. Highly rec. if you need multiple jets and needle options to cover a wide range of altitudes and temps

Research a little guys...
Yes, this is a "Dynojet" kit with FMF stickers. But you guys would be remiss in thinking you can buy the individual jets and achieve the same results. Most of the money goes towards R&D of the NEEDLE, which is world's apart from a stock needle. That's what you really pay for with a Dynojet kit. Each needle has been designed and dyno tested to be the best it can possibly be for your specific application. If you must have a larger pilot, by all means buy one. Most machines won't. I have been using these for over 20 years, no problems whatsoever.

Got it the first try
Very easy all in one kit. Follow the directions and do it once. Jets are listed according to elevation and are dead on.

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

Anyone know how big the jets are for a polaris predator 500?
A shopper on Feb 22, 2017
BEST ANSWER: 45 pilot
148 main
I have a 400ex that is bored 20 over with a stock pipe. I currently runs very hot. Will a bigger jet fix this issue?

Thanks
Tyler H on Jul 15, 2018
BEST ANSWER: No that will give your bike more fule remember that.maybe a little bit bigger main jet will help but it wont stop your bike from heating up man
I have a 06 crf450x with 06 crf450r head and cam with standard exhaust and air box, would this be an ideal kit to use?
Jason A on Oct 29, 2017
BEST ANSWER: THIS JETTING KIT IS MADE TO GO UP IN JETTING NEEDED FOR AFTER MARKET EXHAUST, INTAKE, CAMS, ETC.
IF YOU ARE LOOKING FOR A STOCK CARB. REBUILD YOU NEED TO GO WITH A REPAIR KIT( NOT A JETTING KIT)

I have a 2003 lt-z 400 with a DG exhaust and it seems to have an issue getting fuel or air will this jet kit work?
A shopper on Jul 13, 2018
BEST ANSWER: Typically just adding an exhaust won’t warrant a re jet of the carb. There should be enough adjustment with your stock carb to account for the exhaust. However if you modified your air intake as well then yes I would recommend a size up with your jetting. Also make sure your choke isn’t getting in the way, it can easily starve the atv for air and make it run terribly.
I got a 02 raptor 660. it has a fmf pipe and k&n air filter with no air box lid would this kit work?
Matthew B on Sep 19, 2017
BEST ANSWER: Yes. Great kit! Complete with good instructions. A must if you have pipe and air filter!
I have a 2000 Honda 300 EX. I just purchased and received this jet kit. However I am concerned the biggest jet won’t be big enough. My 300 is bored .020 over wiseco piston, milled head, hot cam stage 1 , dg full exhaust, UNI open air box. I’m running lean at mid RPM. If this kit isn’t the right one where can I go bigger?

Nowhere in the product description does it say this kit is for only slightly modified engines such as exhaust and air box. The instruction clearly state this though.

Thanks
Wesley H on Jun 21, 2019
BEST ANSWER: I have a 2005 400 EX with FMF Exhaust and stage 1 hot cam. I used the FMF Power UP Kit, I didn't need the biggest jet in the kit. My 400 runs great at all ranges. I hope this helps you.
Is this kit good to use on 98 warrior 350 aftermarket exhaust, knn filter with no air box lid? Looking to go ride in glamis and need to jet for 700 ft elevation.
Jaime S on Feb 19, 2018
BEST ANSWER: This kit will have a variation of jet sizes and this kit should cover what you are looking for.
Does this cover the jets for my Yamaha warrior if I buy the whole system?
Taylor L on Nov 22, 2016
BEST ANSWER: Yes, if you purchase this for your machine, it will come with the parts necessary to get the best performance out of your machine.
