I have a 2007 WR450 with about 425 miles since new. I thought that I would check the valves and have found that they are out of spec so will need adjustment. However, when I align the rotor mark with the mark on the casing through the inspection hole the punch marks on the camshafts to not align with the cylinder head surface. The punch marks on the camshafts look as if they are level with a spirit level and not the surface of the cylinder. When I turn the crank so that the camshaft marks are level with the cylinder the mark on the rotor is about 4mm past the mark it should be aligned with. I have taken a picture of the camshaft marks showing how they are out but I don't know how to upload the photo (can anyone help). It is very unlikely that anyone has dismantled the engine or even adjusted the valves given the low mileage and the way the bike was when I found it. Is it possible that something is wrong or is what I am describing normal. The bike was not running too great but not running that badly either. Any thoughts or advice would be greately appreciated as I'm not sure what to do now.
