Stripped nuts and bolts
I was going to adjust my valves before Thanksgiving, but I remembered that I had stripped the nut on the inspection cover for the ignition timing and the nut for turning the crank. Most everything on the old CBR is steel, but the inspection cover has a cast-in nut and it's aluminum. I had stripped it when I wanted to check the ignition timing several months ago.
After two weeks of below-freezing weather, I decided to work on the bike today. I had a new inspection cover and new valve cover gasket. I have some easy-outs, but nothing to take off a stripped nut. On Black Friday, Sears advertised a bunch of tools on sale, but only until noon. I wanted a "Bolt-out" set, but one set was odd numbers and the other was even numbers. The stripped nut was originally 17mm, but it was so stripped I bought both sets.
Normally, I would put a set of vice grips on the nut and leave it as is, since it's covered with Honda's slider cover. But with the nut recessed, I couldn't even get a vice grip on it.
The first picture shows the Craftsman Bolt Out base set. The second picture shows the stripped nut on the cover. The third picture shows the fluted design of the Bolt Out. And the fourth picture shows the new cover with the recessed nut. It didn't work perfectly though. The #12 was too big and spun on the nut. There was no #11, so I hammered on a #10 and it spun right off. The valve adjustment took a lot longer.
