Hey all, I'm new to the yamaha venture and so far the wife and I love the bike, the question I have is after doing the 600 mi. oil change using 15w-40w rotella the engine has some valve ticking on cold start up then goes away in about a minute. Is this a normal thing on this engine, or do I just have a valve set a little loose, oh yeah the bike is an 09. Thanks for the help.
