Japanese Industrial Standard (JIS) Screws

I always thought the screws on my Kawasaki where made of soft cheap metal, because I always was rounding out the heads with my screwdrivers and I have replaced a lot of them with allen heads. As tool geek I was shocked when I finally learned the truth; I have been using the wrong screwdriver on every screw on the bike. These screws and all screws that have a dot on head are Japanese crosspoints and you need the proper drivers. Available here and here.

Here are some examples of the screws with a dot and these are just from the carburetor. As you can see some of these have already been damaged by the wrong tool.

Here's an example from the master cylinder.
