As we all know, the Big K is a Japanese company and all the fittings on your bike are therefore metric. Many of you probably already know this, but there is a major difference between a Japanese phillips head screwdriver and an imperial (US) phillips head. The two major differences are in the blade angles. Basically the tip of a JIS driver is shallower than that of a US version. Also the sides on an individual blade tend to taper slightly narrower on a US driver where the JIS version has them parallel. This will cause the US driver to "cam out" or slip, thus buggering up the head of the JIS screw.

So where do you get JIS screwdrivers? Not at Sears, Lowes, Home Depot, Northern Tool, Tractor Supply, etc. I bet that you will be hard pressed to find these drivers at any local store unless maybe they are special ordered through a bike shop. By the way, that usually gets really expensive. I have found a place online that has these drivers at good prices and free shipping. See link below.

This guy is a small business in Michigan. So far his customer service has been tip-top. I ordered the short 1/4" HEX drive version for $10. I will see them in a few days.

Here are a couple other places with some other options on these drivers.

I do not work for any of these companies, I just thought someone might be looking for these things. I only know of a few phillips head screws on the bike, but you really don't want to bugger up the head on one.

Hmm, interesting. I've been around industrial machining and metric stuff for over 30 years and did not make the correlation of the screwdriver thing.
So, I went out into the shop and pulled the tool kit that came with my Lathe, the kit that came with my mill and the one for my Taiwanese grinder. Yep, they are different than my Craftsman #2 and #3. Very similar in appearance until you look closely at the angle as you mentioned.

I bought a set in the second link and use them on the bikes. Can't hurt to have the right tool.
Yeah! Back before big-K made a change, the screw holding the air filter frame in was JIS phillips. I messed it up so bad I had to use a back-out tool to remove it in the end. For a while I just used a regular philips on which I had ground the tip down a bit. This works okay, but can still cam-out a little to easily because of the side angles. I finally decided to get the real deal the other day when I had a little trouble getting out the screw holding the coil cover on.

I bought a set before I changed my airfilter after reading all the problems others had with the retaining screw.......I've since used them more than any other screwdriver working on other peoples japanese machines.......a solid investment in no stripped screwheads. I wish I had bought a set years ago!

Yes, thanks from here too Jeep Pirate for the excellent "heads up" on this. I always wondered why I often had trouble removing phillips head screws on my bikes. Interesting that these are so hard to locate. I guess I can understand why Home Depot and Lowes and the rest might not carry these, but I also just did a quick search through some of the major motorcycle online suppliers... Dennis Kirk, Cruiser Customizing, J&P cycles, and none of them turned up any search results when searching on JIS screwdrivers. Heck, I'll bet even the popular Cruz Tools kits don't even have them included. I did locate some on Amazon, but they mostly look like the smaller jewelers style of screwdriver kits. I appreciate you posting those links you found.

No. I never intend to be politically correct a day in my life. So just get over it. However, I am an equal opportunity offender. I'll laugh at any social group you name. I even enjoy laughing at big dumb rednecks like myself.

I finally got me a set of these, the ones from Ika's Web Shop in JP's second link. They are Hozan brand, and look and feel really well made. I haven't had an opportunity to use them on the bike yet, but I'm working on a wide-format EPSON printer at work which is Japanese made. I was having a somewhat difficult time using our admittedly sketchy hand tools there. So I brought in the Hozan JIS set and they really do make a world of difference. A really snug, solid grip into the screw head. I'm very glad I got these and will probably also now order the hex drive set too. No more cam-outs (a term I never really knew about until this thread).
Now I'd like to find a nice little case of some sort to keep them in.

I have a specialized bag I can sell you for the screwdrivers. I'll even pay shipping. ;) :D

Question ? How many sizes of screw heads are on the bike that the supplied screw driver will not fit. I have forced my self to whip out the tool kit for most things, my biggest problem is remembering that the custom goodies are standard and not metric, hence having to remember which set of allen wrenches to use, actually called the manufacture of the BREAKAWAY THROTTLE grip once only to be told, the allen is not metric, really felt like a shum dit :eek:

I don't know the actual sizes of phillips head screws that are on the bike, but the main ones I know of are the battery bolt, the screw holding the coil cover in place, the screws holding the tool box in place, the screws holding the side covers in place, and the headlight adjustment screws. I have been able to use what I call medium sized drivers for all but the headlight adjustment screws. The headlight screws are small and you need a long enough drive to reach them up inside the bell.

As for standard fitting on the accesories you have added, I run into the same problem. I have taken to keeping a little bag of standard wrenches in the appropriate sizes to fit just the accessories. I have one allen wrench for my windshield bolts, one for my foot pegs on the highway bars, etc. Also, when mounting my driving lights, I threw out the stock fasteners and replaced them with stainless steel metric fasteners so that I wouldn't have to keep standard wrenches on the bike. I am one of the few folks who wish we would all just switch to metric on everything and be done with it.

what about the screw driver that comes in the tool kit? would that not be the proper one for the screws on the bike. I know its not the best, but it would prevent mucking up the srews on the bike. Inever reilised there was a difference....thanks for the info. youlearn something new everyday on these forums.
