700 X2???'s

I have a two issues with my 2008 700 X2.

1) Does anyone have a lot of problems with heat out of this machine? It pretty much burns my right leg along the muffler even though it has a guard over the muffler pipe. I have problems with my kids on the machine burning their leg and melting their shoes. I am concerned that in the winter, when wearing a snowmobile suit it will melt the suit. Has anyone put a guard over this or figured out a way to get around this problem?

2) Does anyone have a clicking noise in their engine when idling? I do not notice it when running, but when idling it sounds like the lifters clicking. My dealer told me this is normal? Anyone else??
