I have a 98 CR250. I just rebuilt the bottom and top ends. It has been running great, cranks easy, snappy response, but it idles funny. After it gets warm, it revs up and down when idling. It doesn't rev high, it just kind of surges. I thought about it being an air leak, but everything else seems fine. What do you think?
