Have the larger jets in to tune it for the intake and exhaust. My Raptor 660 runs great now and is tuned properly. Very happy with this kit.

Wake up your Dirt bike
My 06 KTM 525 was sleepy in the performance area. With all the mods people were saying to do to the carb I was very hesitant to do anything. After much thought (too much) I popped for the FMF kit. After opening the box the first thing I noticed was the funny looking main jets. The kit I had did not have Keihin jets. It did have an adapter that you have to install first, then use the supplied FMF (dynojet jets.) Word to the wise, a 155 DJ jet is not the same size as a 155 Keihin main jet. There is a conversion chart if you want to compare them. I kept my Keihin main jet in since I had already jetted the bike before buying the FMF kit. Its the FMF needle that powers up the big KTM. It went from the friendly, sleepy power to snappy, power now. I used to struggle to get a 2nd gear wheelie, now it climbs for the sky in 3rd. You wont go wrong with this kit. If you only do 1 mod, this would be the biggest improvement. My bike has a slip on (end cap on) to derestrict the exhaust and the FMF kit.

Get a Jd kit if you can
Not ideal for most applications unless it's your only option.
Proprietary jets that have to have an adapter, vague directions,
Fit and finish questionable and lacks certain jets that you would expect for a multi stage kit ( specifically pilot jets of any sort).
If it's your only option it WILL work but not like a jd kit at all.

Awesome!!
Installed the stage 2 jet kit when I rebuilt my motor along with a uni filter and a vented airbox. MAN did it make a difference! Would recommend to anyone that's looking for an inexpensive way to add performance to their bike. Just remember when you add more fuel, you need more air!

A: Jets are not exhaust specific. These are FMF branded Dynojets. Profile your machine and a package with the appropriate sizes for your machine will be identified.

Q: Hey so I have a 04 banshee with the 396 (I believe ) Athena kit . And I'm having troubles getting fuel , mostly after full throttle. Will these jets work with the 396 ? Also which reeds do you suggest ?

A: For the best jetting or tuning guides, it would be best to check out your owner's manual. These jets will allow you to give your Banshee more fuel as it would need from the kit you put in it. You can also call the Motosport Gearheads at 1-888-676-8853 for technical help as well.

Q: Am I going in the right direction with this power up kit. I have a Honda 2007 trx400ex. With a Two Brother M-7 slip on exhaust. K&N air filter, and adding 6 UNI Airbox vents. AMRracing-stage3-CDI-revbox. Which is best Fmf-kit, or Dynokit, or Moose kit?

A: All the jet kits are very similar as the Moose and Dynojet are basically the same kit. The FMF kit is a great option as well. All 3 are great products and you can't go wrong with any of them.

A: Not directly. If you bike is not tuned correctly it can cause over heating which this can help with due to having larger jets to get more fuel but overheating can be caused by multiple reasons.

Q: Hello, I have a DRZ-400s that is hurting carb wise. I have the Ikuni carb (29FB T271) and Yoshimura off road exhaust from front to back. I'm at 10,000 feet. How does the aftermarket exhaust effect your jet kit? And why adapter as people have written?

A: You would need major jetting not only for the exhaust but your elevation. You're adjusting and tuning your fuel/air ratio to ensure optimal performance. I'm not sure of any adapters you are referring to.
John
Q: I recently had a full yoshimura exhaust on my 2004 yfz450 and it ran great. I now switched to an FMF power core 4 with a power bomb header and it runs very poorly. The quad bogs down and needs different jets. Would this kit make my quad run good again?

A: It should all work for your purpose, you will need to make the adjustments to the jetting for your set up and for your climate, etc. but yes it will work.
