Thats the general rule, give or take a couple MPH maybe. At 50 indicated you might be doing 46 to 48. A GPS Speedo app on your phone can help you track the difference.

That depends on a lot of factors, but a good starting rule of thumb with most of these motors tends to be around a 105 main jet with no other mods at lower altitudes. Pilot jet depends on what style it has, but typically the most common sizes are 36,38, or 40. for a Keihin jet. It really helps to know your starting point to be able to make any suggestions.

Generally that can help improve flow a bit. Removing the catalysts from these bikes if often even more effective in terms of opening up their breathing.
