As far as how much, thread will have some information...but you need to try and determine how much the oil has so you don’t overdose your oil. Tough to do. Some of the links mentioned in this thread have outdated info now and I haven’t looked at them lately. But, you should be good on some of the information if they state the grade oil tested, SH, SJ, SM, etc.

If you are using a good motorcycle oil I wouldn’t expect to need zddp added. Are you looking to dose higher for break-in?

David,I'm running Shell Rotella T4 15/40 standard non-synthetic,not sure if it has quite enough zinc..

Not trying to re-start an oil thread...but Mr Rieck suggested Motul 300V Synthetic Motor Oil - 15W50 to me as it apparently has a high zinc content already so no need for the additive. Expensive oil, but I don't really put that many miles on the CB, so its only a yearly expense.  However its a built engine with go fast parts...so not sure same applies to original stock.

I would just like to add a small amount of it to the standard Shell Rotella T4 that I always use for extra protection,but not too much.

You are fine with the Rotella; I've used it in my CB, as well as my Toyota truck.

Agree with Scott, you are fine with the Rotella.

 The Top alcohol racers I know use 70 weight valvoline racing oil and add a few quarts of differential oil to a barrel due to it's high zinc content. When it gets milky from alcohol contamination they heat it in 5 gallon cans with a nitrous bottle warmer with a cloth over the top and cook the alcohol and moisture back out of it.
