My 04 Aero had 8450 miles on it when I bought it July 2013. Since then I have put 10K+ miles on it. It has since the day I got it back fires when decelarting unless I completely close the throttle, runs rich plugs are black and sooty looking and have never gotten more than 32 mpg. Ran lots of Seafoam through the fuel system, replaced the air filter, replaced the plugs. I have taken it to two highly recommended local shops and still no difference in spite of the first shop keeping it for 3 weeks the second one for 5 weeks. I have ~$400 in shop charges so far and would gladly pay the right shop to have it running right. First shop said they fixed an intake leak next shop said they cleaned the main jet in the carb. Having spent my entire working career fixing airplanes and autos I am capable of rebuilding the carb but frankly don't want to spend my precious free time doing so. Does anyone know where I might take the bike in the central east of Florida to finally get it fixed? I live in Sebastian which is almost exactly half way between Miami and Jax.
