I am somewhat concerned by the ever increasing cacophony of sounds emanating from my STS SE5 engine compartment during the 600+ mile break-in of my Spyder STS SE5 V-twin. Also a fellow rider noticed some wisps of blue smoke coming out of my tail pipe as I ran through the gears at partial throttle. The sounds coming from the engine compartment include valve tappets' like noise and whirring sounds. The engine oil has remained at the full mark. Are these behaviors normal for the V-twin engine? I sure could use some reassuring, if it is warranted.
