Firstly....
to the site. Real nice bike you have there too.
So.. the "bag of hammers" is pretty typical on a cold Bandit - especially if the carbs are still stock. You'll get a lot of improvement with a Stage 1 jet kit and slip on. Mileage, cold starts, power - all improved.
Even with all that my bike still sounds scary when cold - especially without earplugs. Once it's fully warmed it purrs like a kitten - a noisy kitten but it just keeps on running.... and running.. and running.
Great find on the bike - you'll love it.
