My 1000 has around 900 miles on it and has been making a fairly loud ticking noise when the motor gets hot. I already have the Alba automatic tensioner and run either Rotella T6 or Amsoil 5w-50 with K&N oil filter. It sounds fine at startup and when warming up. Just when the motor gets up to operating temp it starts ticking almost like a lifter tick or loose valve clearance. I checked valve clearances, and all were within spec except one exhaust valve that was .011. Would that make it tick, or does anyone have any other suggestions?
