I was almost to 17,000 miles and knew it was past time to check the valves. I had already done an air filter and spark plug change so dove right in to the valve adjustment. Everything was good, two intake valves were at .152 mm, on the edge, so picked up two spacers at 2.95 mm and installed them. Everything looked good so it was time to torque em down.... One of the bolts snapped and not in an easy to reach way, about where the threads start so it can't be easily gotten to. So now I'm trying to figure out how to get that thing out... those bolts are hard and that aluminum is soft so I'm gunna need some better bits and maybe some advice. Any ideas guys?
