Keep hearing members praising the JIS drivers, Japan's revenge on the world. I have never used anything but Phillips head screw drivers on my bikes. Today, I went looking at all my drivers and found that I had 4 JIS in a kit, interesting? Then I thought, all Jap bikes have a tool kit, checked mine and sure enough, 2 JIS drivers in the kit. The moral of this story is this, if you have a Jap tool kit in your bike, you've got a JIS driver. PROBLEM SOLVED
Good find.... I believe its an SOP that in every bike you purchase should have a tool kit included. Good for you that you have a JIS driver.
I'd be interested in view on aftermarket tool kits for bikes. I found a simple one from the UK some time ago (Robin was the name I think) and added a allen key set and works OK but can't find them anymore. Any suggestions? On the JIS screwdriver thing I am a convert - they grip a phillips head screw like me with my beer at the pub on a Friday. Haven't stuffed a screw head with them yet.
