Hi everyone. I have a 99 Monster 750 with approx 11,000 miles. Been riding for about 15 years but this is my first Ducati and I'm loving it so far. My question is that when I first start the bike I hear a ringing type knock in the front horizontal cylinder. After the bike is completely warmed up I don't hear it anymore. Some people have told me this is normal for that engine but I want some opinions from people with experience. So is it a normal noise? I just had the belts changed and the valve clearances checked. Thanks guys.
