One owner 2007 ST3s ABS with 46,000 miles that has been dealer maintained - until now. I'm using the Gates Carbon Drive app on an Ifone to measure belt tension on new belts from Desmo Times. I'm measuring the belts cold with respective pistons at TDC (verified with an endoscope). I measure the horizontal belt, then rotate 270 degrees counterclockwise to the crankshaft mark for TDC for the vertical cylinder. I record the values on a spreadsheet, then rotate the engine 10 revolutions and measure the belts again in the same manner. I'm getting some variance in the belt tension measurements, but average 109 hz for both the horizontal and vertical belt. This is within the new belt spec of 110 hz +-5. When started, the engine sounds normal. PROBLEM: When ridden, I hear a very noticeable turbine-like whine sound when above 3000 rpm that follows engine rpm and appears to be related to the new belts. I've had the belts changed at regular intervals and have not noticed this whine sound after a dealer service. What am I doing wrong? Thanks in advance for any wisdom that comes my way.
