Are you running on original pipes or have you installed aftermarket pipes that are louder ?? I had the same problem with aftermarket pipes and come to find out my carbs were not jetted the way they were supposed to have been done when I installed the pipes.Also there are two chrome tubes starting at the front of the engine going under the seat towards the rear--- there is a rubber hose connection connecting each side .You should disconnect these hoses and bypass the tubes-- in other words use one hose to connect the front two tubes together and the other to connect the rear tubes together , its some sort of early emmission thing that will cause some backfire

here is a good related post from another user i came across with:
When I bought my star 1300 I noticed that the clutch
was making quite a racket. So I took in to the dealer, and they told me
that it was normal. Well after a year that dealership had sold, and the
new dealer checked into the noise problem that I had been hearing.
Anyways what they found out was that Yamaha knew about the noise, and
had a retro kit that fixes this. It consists of new bearings a couple
of gears, and the whole clutch basket. I was told that there isn't a
recall on the 07's. But if you complain, they will fix and replace the
parts for free. I saw that the parts at dealer cost were 350.00. and
who knows what the labor would have been. I finally got mine fixed and
it sounds like a nice bike now. Thanks Yamaha. I also put on a set of
cobra speedster longs, and a fi200r fuel management system. Made the
bike sound better than a harley. It also took out the pulsation that I
used to feel.

I would be looking again at the cam chain tensioner. I have replaced 2 on my 05 so far and it was doing the same thing. the other known problem for noise in the engine like that is the valve guides are know to wear prematurely on 05's and the 03 and 04. Yamaha knows about the problem and will fix it under a one time warranty even if you do not have the extended warranty on the bike. Make sure you talk to the dealer about premature valve guide wear.
