Rmz450 is it normal?

[dadpoppagee111]

I've had my 2006 rmz450 since December changed oil and sorted cam chain strait away done about 2hours on it and it seems to have developed some engine noise and vibrations well I think it has I don't know if it's because I've got used to the bike or what the problem is I have no previous 450 experience to compare it to I've read the 450RMZs do make quite a bit of engine noise what should I look out for or worry about thanks dadpoppagee forgot to mention I tightened the chain before I last went out on it could that cause a change ? Thanks in advance

what chain u tighten lol? cam chain? wheel chain?
when u last have it shimmed? piston?

Tightened the wheel chain and the cam chain and I had a bit too much oil in it i sorted the oil and I re did the cam chain it seem much better I just got a feeler gauge going to check the clearences if they're out get a shim kit if the clearences are out could that cause some noise I don't think it's the piston it has tones of compression and the man I brought it from wasn't a noob and he's loaded so I'm pretty sure it's been looked after if the rest of the bikes anything to go by then it's defanatly been look after
