Motor noise?

[MXD]

My Apex just turned 2200 miles (06 ER) and on start up I hear some knocking from what seems to be the clutch side and it fades away with in seconds. The sound or pitch of the motor has also changed this year but the sled is faster than ever. I am seeing 118 on the dremo where I would only see 106-110 in years past. Could this be the exhaust donut issue?

Could be. The last straw for me was what sounded like a lifter tick. I had several bouts of strange sounds from the engine area, and all are gone with the new donuts. In fact, I'm amazed how quiet the engine really is, considering the substantial valve train it has.

Are they easy to get to?

Although my sled is on its 4th season, it only has 2200 miles on it

I do have almost 2 years left on my YES. Hopefully it will be covered.

Something is not right, sounds like donuts. I would take advantage of the YES and take it to the dealer.
