About dynos....do u jus rev all the way in first or do u drive it out?
to dyno a car would u drive it like u racing down a street or u jus top out in 1st?

Usually you use 4th gear and pull it through the RPM range for a power reading. You can do multiple gear runs looking for problems if you want.
