I'm running Mikuni 28mm flat slides with 25 pilots,and 330 mains,needle in the 3rd slot (stock slot).My mods are in my sig and I'm about 700' above sea level,and run 110 race gas mixed with Motul 800 at 50:1.I have great top end,but I have a mid range bog.Any one have any ideas to make my bog go away???
