Stock spur gear?

[Spn133]

I'm running 20t pinon with stock spur gear. The change of the stock tires to belted killed my top speed. Thinking of going to a 22t pinon and a smaller spur gear but have no idea what the stick spur is or how many teeth to go down to get big top speed on belted tires

Factory spur gear is a 46t. Not sure if you're going to be able to go smaller - may need to make a spool for the center if you're going to plan on speed running it. Kind of a big chunk to speed run though.
