Welcome to the forum!
I'm not sure what you mean by "tapping off to cruise". Can you give a little better description? By "missfire" are you describing a "miss" as in it's only running on 3 cylinders, or a backfire through the carbs or exhaust? Are you experiencing the missfire under light or heavy acceleration? Is it exhibiting any other symptoms? Did you change anything before this started happening?
Before I would suspect anything with the carbs, I'd check the condition of the spark plugs, fuel filter and air filter. Change them if it's been a while or if they look questionable. If they're ok, I'd add some seafoam to a tank of fuel some say a full can per tank, I'd say at least a half can per tank for cleaning), run it for at least 10 to 20 miles at all engine rpms including letting it idle for a while, and park it for a few days. Seafoam is not a miracle cure for everything but in my experience it does a pretty good job on cleaning the insides of these picky carbs.
Give us a little more info when you get a chance and let us know what happens.
On edit, I just noticed your address and realized that Seafoam may not be available to you. I'm hoping someone on here can reference a similar product available in South Africa.
Best wishes,
Steve

Is this a new to you bike?
Has it had a period of sitting recently for a time?
Have you changed the gas filter?
Did you have the gas Petcock turned on while riding?
Was the Petcock left on while sitting? That could be gas getting by the float valve and into a cylinder.
