Hard to start and poor runmning after tuning

please help, today my bike went into the local dealer for tuning on rolling road. They have changed the main jet and and the slow speed jet? On the air fuel ratio chart at around 6k revs the peak was going way high, weak i believe. They changed the jets to try to overcome this. The graph afterwards was a little better but not perfect. When I got the bike home I tried starting it and ran the battery flat with it not even firing. I then ran my leg flat trying to kick it over and then finally got it going once putting a booster pack on it and turning it over for ages. The bike was deffinately not this hard to start before. When riding the there is a lot of popping and spluttering when i let off the throttle from high speed, also the bike will hardly idle now? What should I do? Does anyone no the correct jets I should be using. My bike is a fs650s 2004 standard apart from ackro can. The bike does perform well when on the throttle though?
