I still have a soft spot in my head for the SL350. I had 3 '71s, the best year for the SL I always thought. It had the double down tube frame, slide carbs, and dispensed with the unnecessary electric start. It had a great motor, if a little lacking in the longevity department. I could easily make it up hillclimbs that the two-strokes would struggle with. I rode my first one all over the Pacific Northwest and into Canada back in the '70's. It was my touring bike, trail bike, commuter, and I even raced it a few times. I had a '64 DuoGlide at the same time, but the SL got far more use on road trips because I could always count on it. Not to mention if I saw a dirt road on the way I was curious about I could check it out with no fuss. I still have some parts stashed away somewhere in case I run into another one cheap.
