Just make sure you're using a good synthetic oil (& not one designed for outboard boat motors). Your engine will love you for this.
After the break-in period, you'll probably want to rejet your carb to a smaller orfice. There's multiple threads on here concerning this issue.........many opinions, just read up and you'll start to see some common themes that create the most success.
Best of luck in your new adventure!!
Also, what is a good ratio for when the engine has finally been broken in?
