Really woke up my 660R!

My Raptor had a fmf titanium 4 pipe with stock jets. It would backfire at 1/4 throttle and not accelerate. After installing the stage 2 jet kit it had power all through every gear. Very satisfied with the kit!

Lots of power

Worked great,came with little screws and big screws. I installed the little screws on the handlebars And the big screws on the swing arm of drz400 and it sure made it faster.
10//10. Would add more screws

Good instructions and great performance

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.

Jetting

What main jet from this kit do I use for my 04 DVX 400

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.

Q: I just bought a 2008 Crf250r. It has a mega bomb header and the fmf factory 4.1 dual exhaust and it’s very difficult to start cold and even sometimes hot. It bogs alittle if I give it a fistful of throttle, would this help?

A: Yes it will, good idea to keep consistent with your air fuel ratio. You may also want to check your final drive.

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.

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.
