My YS110 was ever so nice. I started tuning it with a baseline setting of HSN 2 turns out and LSN 2 turns out. Remember the LSN is an air bleed,so closing it makes the engine RICH i.e. less air. On a 16x6 you should keep her to about 9,500 RPMs max. That ought to keep your engine temp to around 95*C or so. Try not to touch the regulator settings.
