Personally I wouldn't do anything. Actually I'd smack it with a dead blow and you've got two options here. It works and you fixed it for free or you cracked the rim and now you are looking for a new one.
I've never cracked a rim doing this and I've fixed a bunch of spoked rims on dirt bikes but I don't want to tell you to go ahead without knowing the risks.
That's a fairly minor dent, I've done much much worse on my 950. If it's not causing any symptoms I'd leave it or have a local place do it. Sending it off you're going to spend a good chunk of cash just on shipping.
We're not out here to rough it. We're here to smooth it . Things are rough enough in town.
