need advice on symptoms - too lean or rich?

Hi people - need some advice on the following symptoms: I live in an area that is currently very hot & humid (close to sea level) My 950 ADV (2004) has stock carby jetting & 2 wings open mufflers. The hotter it gets, the worse the bike runs. It idles but has a big flat spot below about 3500 rpm, where on a steady throttle it misses a bit. It also backfires a bit on the overrun when you crank down a couple of gears. When the weather is cooler it runs better, without these symptoms. Whenever throttle opened right up, it runs fine regardless. Ive got a facet fuel pump & DNA air filter & run the bike on 98 octane.
Do these symptoms indicate too rich or lean?
Many Thanks

Nick (wantok)
