carb boring

If I remember you can only bore a 26mm out to 28mm.

Why bother you can possibly pick up a 28mm cheaper than the price of the boring.

Larger carbs allow a greater amount of air to flow.

If you go too big on a motor that only requires a 26 or 28 it will slow down the air passing over the venturi and can make jetting difficult.
