Worn out Bushings and Clanking at an iddle

I need some help on this. I have just had my 07 Sportsman 700 serviced and noticed 1 bushing missing and had it replaced. Now when I idle and even drive it down the road I’m still hearing, what sounds like a high pitch clanking. When I hit a high RPM it does go away. Still it is very noticeable and you can hear it from a distance.
Is their a diagram of where all the rubber bushing are so I can start locating where they are?
Does anybody have any ideas what it might be?

Please let me know and I thank you for all your help on this.
