At guess it's cos you want the hot side of the head getting the most airflow, plus fitting in one of those boring airbox things is easier.

Triumphs were easy to reverse the head on because they had twin cams, and symetrical head and barrel stud patterns. Not so easy on unit engines because of the 9th stud, and there was an oil feed to the exhaust cam followers in the barrel flange.

This is my brothers chop in about 1971 or '72. He later fitted some short mega's, and some heat shields as he burnt his legs at stop lights. It did miss and fart in the rain, and I think he fitted air filters at some stage. The engine was out of a speedway sidecar, and the most powerful 650 Triumph I've ever ridden, although these days with modern stuff they could make one with double the HP.

Exhaust length is also an issue e.g. too short. Check out the exhaust on the new YZs that have reversed heads. Doesn't go straight back, but meanders all over the place before getting to the muffler.

It’s an artform getting 2 stroke exhausts right. Length is really important. Not so with much with 4 strokes though.

I like it, some proper mud guards on it and higher bars and I'd ride the hell out of it.

But I ain't trimming my beard, rolling up my jeans, wearing thick rimmed glasses or riggers gloves.

You know I read on a thread recently

"A good Rat Rod is actually very meticulously designed."

Wouldn't that be an oxymoron?
