I use a high quality hollow ground gunsmithing bit set, and the phillips bits from there work great -- about $20 from pachmayr.

If not for that, I'd definitely have a JIS set, but the lock I get on the screws from using the correct sized hollow ground bit is like no other.

Now that I have them, I wish I had em sooner.  But I always used my impact driver the first time loosening a screw in anything.  I got the vessel jis impact drivers...they are wonderful.  Before those I found a deck screw bit that fit well enough to not cause damage, but I still worried.
intrigued by the wail...seduced by the scream.

about 30 seconds with the bench grinder turns your philips japanese...I mostly just use the impact driver and/or a oem tool kit screwdriver and the only time I have a problem is when that puppy ain't comin out in one piece no matter what you use.

JIS all the way!
It really makes a difference with the smaller screws, especially carb screws.
I got a nice 4 piece set from Mcmaster Carr a few years ago for about $15 but they no longer carry that set/brand any more.

JIS screwdrivers as well as JIS impact driver bits. Anything else (when dealing with stock fasteners) is an exercise in futility.

JIS is a must for those tiny screws when you're at the carb slides to change the needle position (if you must).
Replace the 16 crosshead screws that hold the floatbowls by ss allen screws by all means.
Furthermore I have replaced two of the 4 screws that hold the left crankcase cover (sprocket cover) by allen bolts.
For the rest, believe it or not, I haven't changed anything (studs at the headers excepted). Even the chain adjuster lock nuts in the rear are still the ones the bike came with, although now, after hundreds of adjustments, they get a bit round.
An impact driver is an useful tool in your workshop.
I wonder why people change all for allen, it's a waste.
Best advice I ever had, you can read in Zen and the Art of Motorcycle Maintenance. Robert M. Pirsig who deceased last month at the age of 88, tought me about the correct state of mind you have to be in when you do maintenance and when it is time for a cup of coffee.

The small adjuster screw for headlight rim and rear lamp still small x-screws, though.

A JIS screwdriver is on my long wish list - but me and all my crosshead screws have survived over thirty years of wrenching without one so it's not urgent! (I'd never even heard of 'em until I joined the forum!)

All three of my bikes have all 100% original screws and I use a $3 impact driver with the tip ground down to crack them loose.

An inexperienced person could quickly wreck all their screws with some ham fisted use of a phillips head screwdriver!

I bought a JIS set from Vessel and recently picked up an older Vessel Impact driver that has the blue steel box...the driver has chrome in a couple places and blue body.
I have an old Sears impact driver but it weighs a ton and the Vessel was at an incredible price 2nd hand.  Just the later came with no JIS bits.
Started a conversation with Vessel US distributor about ordering the set that came with it as they had long versions of the bits which are handy for giving you a tad more reach when using.

I would recommend you buy the replacement bits that Motion Pro sells  in 2-packs for each size...they came out with a new T wrench with JIS #1, #2, #3 bits that are 1/4 hex driver bits about an inch long.  Perfect for ratcheting screwdrivers or a screwdriver bit socket...they have a locking ball and magnet so they don't fall out if the mechanical part does not hold them.

Vessel sells a replacement bit set for their impact driver handles as well, if you have an impact driver and don't need another...  they can be the 5/16" hex bits and ou can replace the bigger JIS bits or buy them.  They are not cheap.  Might just be better in long run to buy the Vessel set or a Megadora with the impact driver technology they sell built in.

Thanks for that information RAF!

I have my fathers old vessel impact driver, but without JIS bits and was looking for these. Looks like I can get them through FortNine Canada so easier for us Canucks. Anyone have an opinion on FortNine for service and stuff?

Oh and as for the OP: yes get the JIS and save your old fasteners.
