Good article here on JIS.
As a public service notice to go along with your excellent DR mod videos I would like to suggest these tools...
This is one of my favorite shop tools and I recommend it to everyone:
Often sold as a set with a drill/driver, batteries, and a charger:
An 18V Impact driver. It is amazing how fast you can strip a bike down... without stripping the screw heads!
With socket adapters, sockets, and a set of screw tips you are ready for action.
It will loosen most bolts 14 mm and smaller, I use a ratchet to break larger ones loose before zipping it off with the driver.
For reassembly I start the bolts, nuts, and screws by hand and then run them in snug with the driver (it is variable speed so it is easy to do without over tightening them) and finally torque by hand.
Using a torque wrench when required.
I think most of us have learned to use JIS drivers on our bikes and NOT Phillips screwdrivers.
If you don't have a set of JIS screwdrivers and/or replaceable tips. Buy them.
Finally, similar to using JIS drivers on metric screws, it is essential that you use metric wrenches.
Yes, there is a difference!
Here is proof.
Now, back to our regularly scheduled DR modification instruction videos.
