If all else fails, read this...you can get a 2 cylinder or 4 cylinder device.... MORGAN CARBTUNE PRO, MOTORCYCLE VACUUM GAUGE. 4 CYLINDER. EASY TO USE, SETUP AND HIGHLY ACCURATE. HIGHLY RECOMMENDED FOR THE HOME OR WORKSHOP. The new Carbtune Pro Uses the same principle as the Carbtune II, it replaces but upgraded and redesigned to ensure better and more consistent assembly and performance. It contains NO mercury or any liquids. Carbtune Pro synchronizes the carbs on Yamaha, Suzuki, Kawasaki, BMW, Ducati, Guzzi, Laverda, Triumph and Honda motorcycles and virtually any other multi-carbureted or fuel injected engine
What you adjusting? The carb or the motion pro? Will adjusting the motion pro automatically adjust your carb for you? (I thought you were suppose to adjust the carb?)
