Hello All,
I have a 07 600 CFI Switchback that is a real bear to start when it is cold and has a real terrible mid range bog. Not a blip type bog at a certain RPM, it is just has poor mid range power. Once it is warmed up and shut off, it starts normally. Rode a friends 07 600 carb and it was much crisper in mid range side by side. Machine has 2000 Miles, owned it for last 500 and seems to be getting worse. Any suggestions? Where do I start?

Thaw it out, bet the airbox if full of snow and ice. Put in a bottle of Iso-Heet, the red one. Make sure the plugs installed are RN57YCC's only! Put in new ones if you have to. Clean the exhaust valves.
