You guys were right again. When suggested that my 79 XR 500 had skipped a tooth on the timming chain gear i dismissed it thinking it would not possibly run. Wrong again! The fact is , the ignition comes off the crank so it could still run but only if valve timming is not off too much. If it were the valves would hit the piston. After driving the bike around the yard now & again i kept thinking the performance is not what it was before the timming chain adjustment incident. I tore it down today. It was out of time by 1-2 teeth. & found the rockers are missing bits of chrome & the cam is not perfect. I will post a want add for parts but if anyone has a good cam & rockers that they would sell, please let me know.
