You should have seen my 70s era Kawasaki 3 cylinder 500 cc road bike back in the day. I’m pretty sure the blue cloud that thing belched at startup alone aired more pollution than a weed eater makes all year. Weight and speed carried more weight than emissions back then. I acknowledge a healthy planet is better, but boy were those bikes fun.
