Sounds like you have the same valve train rattle as me. Had mine diagnosed by my mechanic as cam chain tensioner, even though it went away as the engine warmed up. They are going to replace @ no charge even though the bike is out of warranty (1 1/2 month). Mine came on real quick and is getting worse, don't take any chances. This will be the third replacement, bike was ridden hard by previous owner, imagine my surprise!!
Good Luck.
