I've read how well a XPR Vortex ECU will wake the engine up but I was blown away. I would definitely recommend it.

Bike is noticeably faster all around but more torque for sure

Great product. Got it in time for our big SX race. Thank you Chad!

Everything was an exact fit and works great!

Works great 👍a must have or your XPR vent elbow on cap is way to loose.

Jumps are easier to clear. Endless power down the straights. Highly recommend anyone to invest if you are looking to level up your bikes performance.

Added the second injector and now jumps that were hard to clear especially when the track got rough are a breeze. Endless power down the long straights. Would highly recommend anyone to get if you are looking for more power in the top, mid, and low end.

100% recommend this kit. Easy install and great customer service. Bike rips. I get a ton of complements on how it sounds, and I love riding it. Coming off a fc350, and honestly the bikes pull similar now. Not missing any power out of the Honda while also maintaining how easy the bike is to ride. 10/10 would do this all over again.

Glad I got it, don’t need to worry about pinching my fuel vent line

Order the whole second injector kit for my 26rwe. Super impressed with the customer service and all their help. Instructions were clear and made the process super easy. Bike runs amazing. Super smooth power band but def pulls harder on top. Feels more like my fc350 did but in Honda form and I love it.

Definitely a must have for your Yamaha

I'm a vet rider, and I often ride on small private tracks. I got the ECU to take a bit of the edge off of my 450. It works great.

I purcahsed this fitting for my YZ450FX snow bike. I had one OEM plastic fitting melt and break and the second OEM fitting was leaking through the o-ring. The XPR aluminum fitting is far superrior to the plastic OEM fitting and should eliminate all issue i had. I have put about 5 hours on it since installation with no issues.

Added quite a bit of power across the board.

Fit perfect
