Not sure if this is an issue or not. The bike just turned 9k. When I start it up to go to work or back home, the engine makes a knocking sound. Like it is starving for oil. After it warms up, it quiets down and sounds good. I'm not sure when I first noticed the noise. This only happens when the engine is cold. This is my 4th bike and I don't remember them making this initial noise.
First off how long have you owned this bike and what year is it?
2ndly what type of bikes did you own previously; or more importantly is this your first fully faired bike?
Fully faired bikes funnel the engine noise up to your head by design and the ratcheting cam chain tensioner on this bike is known for being lazy and slow to respond to cam chain wear which will make for a noisy motor on cold start up.
The tensioner can be removed for inspection to make sure it is not stuck and there is a simple procedure to help it take up slack a little sooner if really needed; which is usually not but it helps some owners sleep better.
Where is the noise coming from? From the left and up high is the cam chain tensioner.
What does it really sound like; is it a true knock, or more along the lines of a loud tap, etc?
