QUOTE="GGR3, post: 245223, member: 5104"]My new 2013 Roadster (275 miles only) has a rattle, hot or cold what sounds like a spray can. If you grab the throttle and bring the idle up to 1500 rpm and hold it there, its very noticeable. Is this something I should be talking to the dealer about?[/QUOTE]
first pull the clutch lever in slightly(not enough to start releasing the clutch) and see if it goes away. you might be hearing the lifter piece rattle. Since yours is so new I doubt you are hearing the noise refered to as the paint can rattle. This was from a bad lot of lower crank gears which was in 04-05 and has been changed. If you still hear the noise after trying what I stated. Shut the engine off and put the bike in gear, then rock it back and fourth a few times it could be you tensioner is about to take up adjustment on the chain. new chains will stretch a bit as they bed in to the chain guide and gears.
