Jay Clark put together this mean sounding 2024 Yamaha YZ250f. Jay built what he believed to be an ideal but reasonable yz250f. Usable power with a little more breathing out of this already great platform. Check out the video for more details!

Jay Clark is a bit too old and chubby for a 250F (his words not ours) however, he loves the YZ250F platform and feels a 450 is too much. So, modifying a new YZ250F with a Dual Injector is right up his and Twisted Developments ally. Jay does wish that Yamaha would make a YZ350F but at this point he figures he will be retired from moto by the time that happens. The new YZ250F has some great durability updates so adding the Vortex and Dual Injector is not hurting reliability and Jay feels the improvements of the trimmer new chassis are a big improvement and we all know the stock Yamaha tends to have the best suspension stock. Race Tech just added a bit for Jay’s more “vet” size. That with some Works Chassis Lab engine hangers and mounts the chassis/suspension feel amazing.

The added instant throttle response with the Dual Injection set up with the suspension mods and this bike is incredible, its no wonder we see the BluCru up front so much at the pro and amateur race scene.
