Any assistance?

I purchased MX Bikes with the intention of having fun, as I appreciate its less arcade-like behavior compared to other motocross games. However, due to the modding options available, I'm considering using it for testing purposes. Specifically, I'm interested in creating bike mods with variations in center of gravity, wheelbase, and other factors to observe and assess the differences in-game. Can these modifications be considered reliable for testing? Additionally, I've attempted to follow a guide on creating new mods but have encountered difficulties. Any assistance or guidance would be greatly appreciated. Thank you.
