It seems like he did but I'm not sure.
At one time, I had an XR650L engine in my '84 XL600. I used a 38 mm Mikuni flat slide carb with a universal Uni foam filter clamped to the carb. It worked fine. The filter did rub on the shock spring though.
The Mikuni barely fit between the tank and frame. I'm pretty sure the stock XR650L would not fit.
