King Canyon to Bass Lake Route 41 or North Fork

North Fork Road, though scenic, is a bit of a goat path. Hwy 41 is much easier to navigate. Also, weather can affect North Fork Road to a much greater extent than Hwy 41.

You do realize you'll be nowhere near Yosemite Valley at Bass Lake, right? It's a good solid 75 minute drive to Yosemite Village from there. You might want to stay at El Portal, inside the park, or in Mariposa (even Oakhurst would be a bit closer).

I would go Hwy 41 north of Oakhurst to Bass Lake RD and drop down, South Fork Rd is county maintained diffinetly not a Hwy if anyone with you gets car sick then stick with the 41.
