70 cc motor 80 cc carb?

[Turner]

I know that there are different size carbs out there.. so my question is... would a bigger carb make my bke faster?

I doubt it for the same reason muscle cars want the right # of cubic feet per minute.

Not to mention the "80cc" carb is likely off a realistically 70cc motor, and could be the carb you already have.

Now if the carb has more mixture adjustment screws so you could get a better tune that's a different thing... or if it comes with a bigger intake manifold (tube) that matches your intake port, and your existing manifold does NOT.

In short, save your $.

There is no such thing as a chinese 80cc 2 stroke bicycle engine. Your "80" cc is no larger than 70cc. I guarantee it. Therefor, both carbs are the same.
