Shift at 9,000 should keep things in the boost range fine. If I don't like it it can be changed with easy to get to dip switches.. This bike's gonna be more my cruiser. 89 will be a Hot Rod if I keep it...
i follow, i also think it depends on the gear, since the 1-2 shift if you shift at say 9200 you may end up at 7500 but the 2-3 shift if you shift at 9200 you may end up at 8200
