Hi guys new to this my 1988 softail after sitting for some time like a week then start it starts to pump oil out the breather stop motor then start again and dose not do it any thourghts would be greatfully apriciated 

There is a ballbearing valve in the oil pump that can do this when it needs reseating.

This should give you some idea  of what i'm talking about.

You can buy a tool much like a tap reseater as well for the job.

Thanks so much guys
