For starters everyone knows the special sound of V4 engines ST 1300 and we can call a "whistle"
What is this noise in the engine? what part of the engine produces the whistle and why ? Ask these questions because my engine sounds louder than other engines ST 1300..."whistle" is much louder than my friends engine and do not understand why....it's likely to change something, to have more engine wear? Sound difference was made between three bikes all different year, my 2003 and my friends in 2002 and 2008.All 3 motorcycle were around the 60,000 km....and all three came to the conclusion that my engine whistled louder. Can someone help me with answers? Thank you
