Knipex Ear Clamp Pliers

super easy to install, works perfect no issues, really brings the 350 to life. Paired with the exhaust flange and the best bang for your buck!

The XRP dual injector kit and Vortex ECU is a no brainer , If you are going to do any overnight basically plug and play modifications on your 250 other then suspension save your money and buy this kit you will be totally blow away with the difference it makes

Spoke with Chad many times he’s unbelievable with the service and follow up customer service he provided I rode ktm 350 many years and wasn’t happy with the stock Yamaha 250f I have to say his ecu 2nd injection a long with his recommended gearing 51 tooth rear sprocket really woke up this bike I have no doubt now about the bike and the price is well worth it every penny with that said I believe it’s check all the boxes and is as good as any of my 350s

Works terrific!

Works awesome!

Chad and this crew did a amazing job with my vortex for my 2024 kx450. All i can say is WOW! this bike rips and it is amazing how their mapping has made my bike not only faster with more power, But simply more enjoyable to ride as well. If you are in the market for XPR mapping, It's the way to go hands down.

Such a simple idea, and it also looks Super Trick underneath the cap cover ! Great Product, Great Company! Just buy it, you will not be disappointed!

Ordered this to replace the auto one and prevent future failure. I know what it says it does but wow it’s an immediate noticeable difference. Felt like 3rd suddenly opened up and I was able to stay in it longer. I put 6 hours on the bike the weekend I installed it and no issues.

Shipped fast, fit perfect and eliminated the vent line kink. Great product!

Quick delivery & easy installation also helps the bike breath a lot more along with my twin air

2025 YZ250F dual injector kit with vortex ECU mapped by XPR. Incredible improvement over stock. I am 215lbs and race A/B Vet off-road. I have a 25 YZ450 and YZ250. With the dual injector and chads maps, the bike feels super light and easy to throw around. The power is so much stronger than before and honestly, I may race my 250f more than 450 now. I can’t believe how much it improved power on just pump gas. There is no more “hit”, it’s just excellent power from bottom to top. The bike revs super fast, can pull a gear higher, and feels fast. Definitely worth the coin if you have it. Follow me on IG @wardognj

Everything about this part is what Yamaha should have done from the start. Exact fit, durable, better flow and looks great.

Not sure how much difference the exhaust flanged made since I installed it at the same time with the second injector and Vortex ECU. The second injector and ECU made a HUGE difference on my 25' Husky FC350!!!!! This bike is very responsive off the bottom and starts to pull in the middle of the RPM range and seems like it doesn't want to stop. The best part is it's not overwhelming........ Doesn't have that blinding pull like a 450 but just s smoother power. I'm so impressed but this set up.!!!

Awesome product, so nice and neat, runs clean and connected

I purchased the full kit from xrp all arrived in a very short time all the way from USA to uk
Very happy about that
Fitting of the kit was so easy and straight forward the kit comes with all the information ie tools required
First start up the bike primed up straight away with the injector working pretty much once the bike started running
The first go on the bike was a local club meeting and to say I was surprised on the power gains is an understatement
Usually in deep ground the bike would take a while to pull through the revs even with a 51 rear sprocket
With the twin injector kit I was hooking gears through corners the kit is unbelievable how much crisper off the bottom and the increase of torque mid to top is amazing
I can’t wait to try stock gearing 50tooth rear to see what the bike will pull like then highly recommend this kit from xpr for the 2025 crf250
