Hey Guys!

I have recently had an rattling noise coming from my engine. It's pretty bad when you first start it up then gets less. When you rev the throttle and let go it seems to make it as the rpms fall back to idle. I'm pretty sure it's not coming from the plastic guards sounds more metalic. I was hereing it also when I was running full out. Are these motors really that noisey?

Only has 54hrs on it and I have had the dealer do the 20hr service: all fluids replaced, valves, ect. I brought it by the Honda dealer and a service guy came out to listen to it and he said it sounded fine, we were outside and the wind was blowing pretty hard so not sure if he could hear it. Oil looks fine.

Any help would be appreciated!

 

I'd be wondering about cam chain tensioner.

I've heard them where they will make noise when you pop off the throttle, kind of a chain dragging on something metal kind of sound...

 

I have a 06 with over 1200 miles never had a noise like that i think jeffinTD is right.
