What would matter if you could put 75 or 90 carbs on a 60? You still need to be able to burn the extra fuel! You will be way faster and more efficient if you are burning properly with 60 carbs then if you had 75 carbs and you are burning too rich! If you can set it up so you are burning golden brown with a 75 or 90 carb it would be unreal! But you will have to find some hotter plugs and the last time I checked I couldn't find better plugs
