Also change oil now. The first oil change interval is way way way to long. Its ready now. Your oil will look like a shiny silver and the filter will be full of shiny silver metal particles. Its time now.
Oh MY GOD WE ARE ALL GOING TO DIE!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I use engine braking all the time, in cages, on bikes, on four wheelers, it hurts nothing.
Its not going to do anything you dont tell it to do. Thats not to say you cant tell it to crash and all, just that it is just not going to come up unless you make it.
Racetec will take your wieght and be glad to do the math to make sure you get exactly the right springs for fork tubes and rear. No problems if later on you decide you need them. Not a problem in the world.
