Tuned: Jay Clark’s YZ250F Affordable Vet Build

Building An Affordable Vet 250F MXer

Photos by Trevor Hunter

In the words of Jay Clark “Kent,” the master bike builder himself states “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 an ECU from Twisted Development and a few other key mods is a no-brainer. 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 ECU or even a 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 and speed. Pair that with some Works Chassis Lab engine hangers and mounts and the chassis/suspension setup feels amazing.”

The motor internals are largely left stock aside from Rekluse Torq Drive clutch plates.

 

This air scoop from 3DP Moto increases airflow into the intake, but adds a lot of noise when riding.
Race Tech valved and sprung the suspension for Jay and was a standout feature for our vet test rider.
The Galfer oversized front brake, paired with a steel braided line, increased braking performance and feel.
These handguard mounts are simple and save space on crowded handlebars.
Jay retained the stock 13/50 gearing using Pro X components with Dunlop AT82 tires hitting the ground.

The whole package was very vet friendly and easy to ride, performing best on Glen Helen’s Arroyo Vet track.
