CHECK: Listen to engine at idle speed for any popping or back firing. If popping is occurring at idle:
Verify the air/fuel adjustment screw has been set to the recommended starting position as described in
above step, then fine tune + or from there until popping stops or improves. (See Tuning note)
TUNING NOTE: Proper carburetor adjusting would include balancing which does requires the use of
carburetor sticks or a set of vacuum gauges. The carburetors must be synchronized in order to achieve
optimum performance. This procedure should be performed by a qualified Yamaha repair technician.
For best results, we recommend the engine be adjusted on an Exhaust Gas Analyzer (EGA) to a CO

Altitude, Humidity, Temperature, Air Pressure, etc. Contact us if you have any questions regarding this
