Hello I'm new in 4 strokes but I have mechanical experience. Today I decided to adjust my valve clearances. They was 0,09 on one intake, 0,17 and 0,19 on exhaust so not bad but the job has to be done. So I removed cams and mesured shims and then I took a look on my cam shaft caps and ..take a look on pictures. http://www3.speedyshare.com/data/567211399/5000528/30174651/S5000528.JPG http://www3.speedyshare.com/data/216168456/5000557/14748243/S5000532.JPG I bought this bike month ago changed the oil and had 4 rides so that's not my fault. The cams are ideal , bearings to. Cam seats in cylinder head are ideal to. Tell me what to do? What I have to replace? These scratches aren't deep. On the intake I would say that the surface doesn't look like a mirror that's everything. And on the exhoust I removed this black burnt oil with my finger nail.
