depends on what and wear you gonna ride. i had 10-10-18 on mine and i believe there a little short as i was alway on the rev limiter and i lost a lot of pull power. i didn't change the spring though just went to 19 and then to 20.

when i first put them on i liked the fact sat lower as i wanted it to but then a buddy that had driven it when it was new said it didn't seem to have thepower it use to so i changed them to 19 in and he said that was way better and when i went to 20 it was even better and 20 and a half was a little to much off the line. however i didn't monkey with any clutching at that time.
