Engine Sitting. Tapping/Knocking after started.
Battery had died in the bike and hadn't started it in a few months. Replaced the battery and it fired right up. However, it sounded like the front cylinder was tapping or knocking for about 45 seconds after starting then oil must have got to the top and now it sounds fine. No more knocking
Anything to be concerned about, that first minute after starting?
Thanks!

When you shut it off a few months ago, one of the lifters was holding a valve open and the valve spring pressure caused the oil in the lifter to bleed off and let the push-rod rattle a bit until the oil pressure filled it back up when you started it. Normal after sitting for awhile. Ride it as long as it stays quiet!

I think you are fine. Might want to start it up a little more often to keep the internals lubed. If you begin to hear knocking at every startup, suspect a bad lifter.
