Hey, nice K0! It doesn't look like a sandcast (I can see the 10th bolt on the clutch cover) but that's a great bike! I see a single cut front fender. It doesn't look to have a rolled rim, but it's hard to tell in the pictures. Honda still sells new 4-throttle cables for those carburetors, and that's what I suggest buying...the Honda cables are nice, and worth the $$. I have the part number if you need it.
