I bought a used 2002 Shadow Spirit 1100C2 with 17K miles and good condition. I´ve never owned a V-twin before (my previous was a 1984 V45 Magna). I think it runs crappy. If it was a 4 cylinder I would say it´s only running on 3. I had the carbs cleaned and rebuilt (professionally), throttle cables replaced, new plugs, new air filter. What else should I look at or have looked at? Or am I just not used to a V-twin?
