got hit with our first storm here in pa burped the sled as rob said level staed the same.put 30 miles on the sled .all i can say is awesome ride ;-). i did notice the oil light come on and off a lot when the sled was on its side a little.and once the sled was cold i opened the radiator cap and there was a big air bubble there.i hope this was the air pocket from the heat exchanger . another thing it was probably stated on here about warming the f7s up before riding.dealer said let them warm up more than the other machine we had.
