Rattling noise
 
Background: 2011 1200N, 1200miles

Problem: When i accelerate there is a rattling noise coming from the left side of the engine. It is not a steady rattling, more like a piece of metal in a glass jar. Only happens when I accelerate rapidly, not on a steady accelerate. Just want to try to fix the problem myself before i have to take it into the dealer. Any thoughts?

Is it a "marbles in a can" sound? Might be detonation...

Pinging because the engine is too lean or too low of an octane?

Just for shits and giggles check your exhaust flanges too just to make sure nothing is broken...like an exhaust stud.

Mine has been making this noise since I've had it. 21k miles later and no problems. I am looking at rejetting the carb and/or adjusting the fuel mixture to alleviate the carb farts/coughs that have increased since I put on the Big Sucker over the off season.

What is the aforementioned detonation" by the way?
