Low hour dual injector kit for a yz 250f. Makes your bike feel like a fully built race engine. Insane throttle response but it keeps your bike reliable at the same time. If that doesn’t make you faster the fact that  you sound like Haiden Deegan definitely will! Comes with everything you need for it. Has the new fuel line, vortex ecu (has a lot of different map options you can change between) and the new air box with the injector in it. I ran it on pump gas at high elevation. Plenty of mapping options to switch between to get the right one for you, your bike and location. Best mod I’ve ever bought for my bike. Had it on a 2021 yz250f. Should fit 2019-2023 though. Might have to call twisted to make sure it will work on your bike.  Only selling because I bought a new bike.
