This is a little before and after video I shot of my friend Jamie Conard's 1991 Yamaha WR500. Originally he bought this beast back in 2017 and has spent the last three years going over every inch of it. In the process he has had the motor ported, head modified, and crank balanced by Eric Gorr as well as replacing the rear swingarm and front forks with YZ components. It really is super fun and potent machine.
