Japanese Industrial Standard

Seriously?
Yep, seriously. Learn to use the search function here. There's a few very well written threads on this forum dealing with the JIS standard. Search for them and all will be revealed.
Many of the hex headed fasteners are the J.I.S. type as well but it doesn't effect the fit of metric wrenches other than the fact that many of the heads are slightly smaller than a normal metric fastener. The perfect example is the M8 size bolt or nut. A normal metric one takes a 13mm wrench or socket while the J.I.S. version takes a 12mm. And there are a ton of these J.I.S. M8's on the 650.

Yes. Definitely seriously. Unless you are in possession of a pristine bike, those JIS fasteners are probably already half buggered up. People, myself included, have been using the wrong tool on them for many years.
FWIW, a Phillips-buggered JIS screwhead can most likely be restored enough to work
by putting a JIS driver into it and vigorously beating on the driver's end with a BFH.
This lets you get the stupid things out so you can replace them with Allen screws.

I have (had ) 2 uncle's who were brothers that owned an Indian dealership in Iowa, Indians and bicycles in the 40s. They were motorcycle mechanics up until the day they bother pasted away. I think they were in their 80s. One was at Normandy...
I can remember hearing them cuss the Japanese fasteners on the old motorcycles 60-70s era

Ah... I see you don't respond well to learning suggestions. Here, let me help with that.... a quick search for jis screws turned up this fine thread by @MaxPete. He's an engineer and university professor... knows his stuff.

If you'll actually bother to read that thread, it'll go a long way to answering your original question.
I know.... being spoon fed is much easier than doing the looking for answers yourself.... but that's kinda encouraged around here.
Hows that for soft hands?
Jim, with those same soft hands, knows how to use a fuel petcock too, and if it has an on and off. You may wish to tread lightly when people steer you in the direction of knowledge. Coming in hot for a new guy
When people ask for help and reply with silly comments, I put them on my “snooze” list. Nuff said.
FWIW I still remember 60's honda engine side covers held on with long 6mm #2 JIS head screws. you couldn't strip out the engine case threads cuz the screws would just stretch til they bottomed. 
Thanks but I'm rarely called hot by another man.....I'm assuming your a male.
That's awful sweet of you JimAh... I see you don't respond well to learning suggestions. Here, let me help with that.... a quick search for jis screws turned up this fine thread by @MaxPete. He's an engineer and university professor... knows his stuff.

You're not my type anyways. I like my men self sufficient

That clinches the diagnosis: Gentlemen, this here is a troll. Shun it, poke it, just don't take it seriously. If it won't go away, Travis will know what to do and when to do it.

Yeah. Although trolls generally have that same foul odor, some have a bit of familiarity to 'em. Ain't that right CC1?
