The only facts I know for sure about the bike are what I have learned in the last 6 months and 200 miles of ownership. The previous owner bought the bike new, according to him. I really have no idea if this engine has been opened up before. I would assume not, though. Without looking at another head, there is no way to know if this one has been "butchered" or not.I think we're all forgetting that the OP isn't the first owner. How do we know some butcher hasn't had a go at that head?
In the pics, the exhaust side is the closest.
I finally got the new exhaust valve and seal. I will swing by on Monday and drop the parts off for reassembly. The head bolts are on backorder so I won't have them for another week or so.
