All caps comes across as yelling.
A reasonable start, I think, would be 45 pinion, 100 spur. The example I found was for the tamiya track. 4.22 overall ratio

might help find combination. Pay no attention to the highlighted red. Just what I was trying at completely different track. But the chart helps.
