Low cost way to increase HP!

Installed kit along with header and exhaust. Huge difference on my 2017 XR650L.

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.

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.

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!

Q: I recently installed a Pro Circuit T-4 S/A Silencer and i was just wondering if i would need to install a jet kit

If a jet kit is needed, would yours suit my needs ?
MotoSportExpert

A: Normally when installing a slip-on only minor jetting changes are needed, if any at all. If your bike is currently jetted properly you will likely not have to make any changes after installing this slip-on. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend installing the exhaust and riding the bike to see how it is running then tuning your carburetor from there if necessary.

Q: Installing an fmf power bomb full exhaust with a uni air filter on a 2014 Honda 450r.. what size jet to use?

A: There is not a specific setting I could give you for jetting your bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.
