If you have any more broken spokes upon reaching Ohio, it would be prudent to respoke both rear wheels.
I started racing a 250 Ducati in 1987. Being low budget meant I sanded and repainted the origanal spokes. It was fine in 1987.
In '88 I had a hopped up motor and was pushing harder as the fever grew. As a result the spokes began snapping. Sometimes 1 , sometimes 2 and if it was bad 3. In one race. And with only 36 spokes to begin with , it's easy to tell by the extra movement in the rear , that spokes were going.
To keep from having to pull the wheel after every race I ordered a set of stainless spokes from Buchanan's. Once they were in ,no more broken spokes.
While you're in the U.S. would be the time to prepare. The roads in Africa aren't likely to be as smooth.
