As a general rule never waste time on cheap carb kits that include jets. For the most part, o-rings are o-rings and paper gaskets paper gaskets, so a cheap carb gasket kit is fine. But you simply cannot trust that the jet sizes and needle profiles are correct and many an owner has gotten frustrated and sold a perfectly good bike because he couldn't get it to run right after 'rebuilding' the carbs with substandard jets that weren't the size they said they were.
Jets and needles rarely wear out, but if you need new ones take the time and spend the money on genuine Honda or Keihin parts.
