Nicely done. Kawi make those 3 bangers in 250, 350, 500, and 750 - the 250 and 350 sounded like chain saws. Pretty popular in high school in the mid 70s where I grew up. Cheap and effective. Not many survived. Blowing through the gears and wheelies were a hoot - tight corners and braking not so much. When they came out, the 750 machs were the fastest accelerating stock bikes you could buy in the world.
