i have to get second gear undercut so it doesn't slip out of gear anymore. i'm planning on a pipe, a tune, and some spray, just a 40 hit. should i get the whole trans race cut, or just fix 2nd gear and call it good? 175 for 2nd gear, 400 for the whole trans. you racers with hot or semi hot street bikes feel free to weigh in, especially if you're spraying.
