o2man98 I think your dead on with the riding style. When the engine is cold the amount of fuel being run through the injectors is almost twice as much under some conditions and remember that all the parts, cylinders, pistons and rings have not all reached the desired size and won't seal as well. So if your one that makes very short trips I would suggest to change oil often. I plan to get my next change tested to see how mine compares. I ride about 30 miles a day in two trips and that should be pretty typical in town driving.
