What does it mean to Rejet a motorcycle?

When you jet your motorcycle’s carburetor, you’re setting the optimal ratio of air-to-fuel that goes into your engine. (This mix is called the stoichiometric ratio, which is 14.7 parts air to one part fuel. In reality, your motorcycle probably performs better at a slightly richer ratio.)

Does slip-on exhaust damage engine?

No, it will not damage the engine if it is designed by someone who has a clue what they are doing.
