I just bought a GL1100 that has been sitting for a few years. The carbs were just rebuilt by a qualified mechanic, but the idle is very rough and noisy below 1500RPM. At 2000+RPM the motor is strong and sounds normal.
I have been told that it is usually the idle jets that need attention, but my mechanic assures me that he cleaned the jets when he rebuilt it. Also, When a jump box is hooked to the battery, the noise and the idle smooth out.
Where should I start in diagnosing this issue? Do I remove the carbs and clean the idle jets again or are there other issues (like ignition) that would cause such performance?
