I just got a 2000 XR-600R off my boss at work for a pretty good deal. He was told by the previous owner that it has a 11:1 piston in it. Even without pulling the decompression lever it doesn't seem like it's that hard to kick. Is this normal?? It seems like it runs strong, but I am coming from a DR350 with a 435 kit, so stock this bike would have more power. Also what things should I look out for and check on this bike? What other performance stuff can I do to this bike to get more power out of it? What about suspension mods for it? Thanks.
