"Japanese Industrial Standard"

JR COOL TOOLS write : A little known, but 'troublesome' standard, the Japanese Industrial Standard (JIS for short) is a Pacific Rim phenomenon.  You can never tell where you will find it now - it's everywhere.  But start with the Pacific Rim:  anything of Asian origin is almost certainly going to include it.  The symptom of the problem is when your standard Phillips screwdriver 'hangs up,' and doesn't feel quite right.  The Phillips driver won't go into the JIS Screw all the way because the corner radius of the screw is smaller than that of the Phillips scredriver!  This is the primary cause of what we know as 'cam-out.'

Stig writes : Bit me today when trying to remove a very small brake fluid reservoir screw on my Forza.
I tried to do right ! - I bought the Honda 4 brake fluid yesterday at my dealer...and asked the 3 guys at the parts counter if they sold a JIS screwdriver set.
They looked at me like I just asked for a quantum leap. "Never heard of 'em." I tried to explain.... "Nope, never heard of such a thing."

I've run in to this issue of very tight fasteners from the factory on both my scooters. If I have not loosened the screw yet, I always expect them to be very tight. They were. My small phillips screw driver could not remove one of the 4 reservoir screws. Tomorrow I buy an easy out and maybe some  torx or allen 4/12mm screws until my JIS set gets here from ebay.

Stig - Still learning...but I DID try to use the rigth tool.

Try grinding the tip of the Phillips screwdriver down a bit. JIS are common on carb screws.
Another option is to go to your local RC hobby shop, helicopter blades use JIS screws.

I found a toolkit at Costco for $100, it's got a half dozen different Phillips head and a half dozen flatblade bits, as well as Torx bits and a few Torx security bits (it has a hole in the center of the bit). Along with SAE and metric sockets, 3 different sizes of ratchet wrenches, metric and SAE hex wrenches, combination wrenches, ratchet wrench extensions, a Crescent wrench, needle nose pliers, etc.

I've never had a screw that I couldn't find a bit for. The thing I like about it is that all the tools snap into the case, then you close the two wings of the case and it's all nice and neat. No tools spread around in drawers.

Update on the stripped JIS  screw in the brake fluid reservoir:
Waited until new Honda parts came, purchased a reversed cutter/grabber screw remover from the hardware store ( autoparts stores had only the kind needs first drilling into this tiny screw ....not good, the extractor would probably also snap off)
Plus a set from county garage.
Using two or three cutters .....screw finally backed out!
I noted that the genuine Honda parts screws were the dot marked JIS screws....while the stock screws were neither normal phillips, nor JIS marked screws.
Replaced all 4 with the JIS.....and not so darned tight!
Also, in parts box were new brake pads, etc. Impossible to see condition of rear brake shoes. Brake reservoir very low,  so if going in to look at pads...may as well rrplace them with new. Muffler must come off, etc.
Writing at Tim Horton....early morning riding.
No sun yet.....will go by and look in window at that pretty People S 250.
Rife safe folks

I also is comeing across this my screws are now striped. so need to get some easy out or gind down to fit a reg screw driver in it.
a few small screws I pull out of my scoot has white foam on theam  so I was thinking is some typ of lock tight.   not cool for those that work on there own scoot.

Alright Stig, after careful consideration and searching my memory I think your onto something here. I remember having issues with carb screws and plastics screws on my Kawisaki that I had. So into search mode I went for JIS phillips screwdriver set. The set I chose is recommended by a M/C site and might be the best deal for a quality Japanese made set. I think it will be a good investment.   http://www.ebay.com/itm/HOZAN-JIS-4-JIS-Screwdriver-Set-4pc-set-/171424618844?

Dadgummit - I gotta have you do my ebay research from now on...I paid more than that for two of them.... same tools it looks like!
I waited for the drivers and the new screws from Honda parts dealer before I went back at the screw.
Getting chewed out on the Honda forum for adding new fluid to the reservoirs.
One was low, so I drew off most of it & added new Honda dot4; then, since the bottle can't be reused for very long, I opened the other reservoir, drew off the old and topped up with new. Careful not to get air in the lines, left some in the bottom of both.
Was told that I either have a leak or a very worn set of brake pads....and that when I push back the pistons for new pads I will have a screw up.
From new, I had the bubble in the site glass....so in 4300 miles the bubble moved to the bottom of the window.....and the "fill line". (I don't have a leak...just wearing rear pads on this combined braking scooter)
So I topped it up.
Of course I know you have to be careful not to over flow the reservoir when adding new pads.
But I guess this Scotsman thinks Americans are too dumb to handle this brake procedure.(I first PO'd him by putting a decal on my scooter)
Some scooter (and moto) forums are about as full of vitriolic pontificators as youtube.
As for scootering - I'm still learning - I hope.
