I have a friend who just bought a 2014, 103 CI it has an engine knock that seems to come and go, dealer said it was normal. I have a 2012 and have never heard that hard of a knock. What's up with that. It is so loud at times people ask him whats wrong with his motor. As i said it comes and goes hear it a lot when you have been riding for several miles and then stop. If you increase the RPM's it goes away. If this is normal I won't be guying another Harley or 103 anyway.
