Well, I've got 2,500 miles on my rebuild. I changed the oil and filter at 500 miles and again tonite at 2,500 miles. I got a wild hair and opened the can on the filter with a tinsnip, there's enough glitter in there to make a juice-bar stripper jealous. There is enough metal to fill the bottom of a baby spoon, is this normal at this point in the break-in? Oil pressure needle has always layed on top of high mark on the gauge. Side note, if your ordering Amsoil, order a week in advance. I ordered a case of syn. 75-90w monday, shipped out of Wichita KS. same day. They found my order somewhere in Kentucky today, I live in Nebraska.
