I had the same issue and was way rich. Agree w/Scar.......but it's one or the other definately. My issue was that I was running stock airbox with cobra pipes but was running a dynojet kit. You don't need one of those unless you're running an aftermarket airkit like a hyper or like in my case now a Baron BAK. Well, at this elevation actually.....I've come to find out that there are many variables to this tuning thing. You'll need to tune the bike to your elevation/climate.
