hi, new to forum so hi everyone, i have a hyper 10sc with a sg.18 engine, i know stock hsn is 4 turns out for run in and 3-3.5 once run in but i cant find any info about the other 2 needles anywhere apart from i did find something saying never touch the msn. i noticed someone else asking about the hyper st which i believe has the same engine but everyone ignored him, please dont do the same to me, if you simply dont know then please acknowledge that
