    Thats about .050 or fifty thousandths, read that FIFTY thousandths of an inch, or in reality - not all that much......

    Unless the airfilter and or airbox lid were changed or removed and or an exhaust installed then stock jetting would work fine or dam close to fine. But, if you let more air in or exhaust out or added a larger carb, then jetting it up a bit would be necessary.
