Yamaha Gas Cap Vent Elbow O-ring Set

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

The second injector and ECU made my 25' FC350 a rocket!! Was planning on racing the weekend I installed but got pretty sick. Next race for me is the end of August. I think with a good jump on starts it will easily hang with most 450. The riding I did with the bike I installed the 13/51 gearing. Just not sure at least yet I'm going to keep this setup but I want to give it time since I know I can pull second and third gear further. Im not young fellow but I really like the feel of the engine compared to my FC450. More user friendly. Thank you

By far the best motor mod I’ve ever done on a 250f

Absolutely fantastic product. Easy to install and you can really feel the difference right away off the bottom end. More connected, cleaner, and smoother power delivery. Stick pipe and stock ecu, the flange cleaned up that disconnected feel off the bottom end.

Fits perfect, no more kinked vent line

The XPR YZF gas cap vent elbow eliminates kinked/torn vent tubes associated with refueling. The elbow simply pressure fits onto gas cap post for easy install.
The elbow has rubber o-ring seals & is machined to allow the gas cap post to spin freely of the XPR elbow. The XPR elbow will ensure that the gas tank is properly vented with fuel flowing freely to the fuel pump!

Very well crafted little modification that helps tremendously

Finally no more vapor lock, yes this is an issue for the 2023 250f. Makes fillup easier too.

I noticed that when I would ride, anytime I got off the bike the tank was starving for ventilation. Well, smashing the vent tube does that lol. After putting the vent cap elbow on, it immediately stopped. Super great part! Thanks guys!

Fantastic quality product just like everything else I bought from them. The fit and finish of this product is phenomenal. This is the way-Yamaha should’ve designed in the first place.

Got the 2nd injector kit with exhaust flange for my 25 KTM 350SXF. It’s amazing. Just more low to mid but still buttery smooth and easy to ride. I think it’s actually easier to ride than when it was stock as with the added hp and torque just comes out of corner better. Can lug it 3rd or rev out in 2nd. It does both amazing. Super easy install. Great customer service. No complaints!

Got this for my 2024 Ktm 350 sxf and noticed it give it a little more snap and sounds like it clean it up a bit to.

Works as described feels like the throttle's connected to the rear wheel and feels more responsive off the bottom end well, worth the money.

Easy installation of the Performance Exhaust Flange, it produced more low end throttle responce and pulled 3rd gear in turns easily. From quality parts and performance to outstanding customer service you can not beat XPR
