Installed kit along with header and exhaust. Huge difference on my 2017 XR650L.
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
This kit had just what I needed to re jet after my exhaust upgrade. would recommend this for sure
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.
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!
Made a huge difference all the lean backfires are gone and notable power gain.
