Rear sprocket advice

I'm working on a 1976 wr360. The back sprocket is junk on it. I plan on riding this on single and two track trails and enduro type stuff just for fun. Does anyone have any rear sprocket size recommendations. How is the hit on these engines? Should I go stock or Bigger? On my '02 cr250 I went to a smaller front sprocket to reduce the hit so I didn't end up in the trees.

What was the stock gearing for the bike? 13/53?

Took a long time to get back here. Lacing up the rear wheel ...oooh my brain hurts after that. Also did the front fork seals.
Maybe someone else can chime in here. The current gearing is 11/53. Is this stock for a 76 wr360?

Rear shocks are junk .... any suggestions?

Thanks in advance

Even if your current 11/53 were correct gearing for your use, you'll probably find that those tiny 11t front sprockets don't last long. I used to waste them in one weekend.

So I'd go up to a 56 in the rear, and see if you can then run 12/56. You'll get better life up front and overall ratio is only slightly taller than 11/53. IF it turns out to be WAY too low, and you can run a 13 or 14 up front, even better.
