2023 Honda XR150L fully desmogged, intake snorkel and restrictor removed, Yoshimura exhaust with the spark arrestor out, and 64.5mm piston/big bore kit with a BBR cam. Runs pretty good and rides fine even on the interstate. Runs out of gearing before I'd say it runs out of power, and even at elevation I'm easily able to hit the absolute top speed of the bike which is roughly 75mph actively banging limiter in 5th.
