I thought the 1300 had hydraulic lifters? Does this have anything to do with the valve adjustments? I have some noise (sounds a bit like valve chatter) on the top-end of each cylinder and I am nervous. The bike has 655 miles on it. It did tend to quiet down a bit after i changed the oil and filter. I used Castrol Syntec 10W40 @ 2.5 quarts.
