my 2007 sabre (1500 miles, oil been changed 2x with honda 10w40)has the engine tick after it warms up. been that way since it was new. dealer/honda says all is well. other sources say clogged oil passage but that does not make sense since it does not make the noise when you first start it. no performance problems, just hate the noise and want to keep this bike a long time. does anyone have any experience with this?
