XR250_RIDER_14 Posted July 8, 2005 I have a 1997 XR250R. I want to get a big bore kit or a cam. Which one will I get more power and response out of. I have looked at big bore kits and cams from XRs only. What am I better off getting without sacrificing my low end torque and XR reliability. And another thing is the cams are almost 200 dollars!! That is ridiculous. They are both about 200 dollars. Share this post Link to post Share on other sites
