Not Impressed

I purchased this kit for my 2017 Honda XR650L and it did help with the lag in throttle response when it gets warmed up completely but by no means did it make a significant difference in power range

Total Waste of Money

I’m embarrassed for everyone that FMF put their name on this. It is worthless. You get a handful of proprietary jets. They don’t even give you real keihin jets, you get a little adapter so their junk can screw into the carb. Horrible design. It’s in the garbage now. Just buy real jets and save money and get better performance. If you’re thinking the proprietary jets are ok, they are not. The adapter has a larger hole than the jet that is screwed into it, creating a big turbulence lip. Main jet should be smooth and uniform.

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.

Answer: A full exhaust system will require a jet kit but i can not verify this is causing the issue. If it is cutting out due to a lack of fuel this kit will provide a selection of larger jets to add more air and fuel to the bike.
