57 yrs old and just learned JIS - nobody told me.

Learned this a few years ago from the legend Cameron Niemela 🤟

Damn it, I've actually known this and more or less forgot. Not this time...just ordered a set of Vessel's. No more stripped heads on master cylinder screws! Thanks for the reminder!

Discovering JIS in my late 40's working on vintage Tamiya rc kits was certainly a game changer.

If mxa had any integrity they’d bash every Japanese brand for using weird easy to strip JIS hardware that “nobody” has the right tools for the same way they would bash tm or ktm for using Torx or whatever oddball stuff tm uses.

Honda fit and finish brooooooo

Rant aside, JIS specific drivers are amazing.

Much like others here, I did not know about JIS.  And I come from a mechanic heavy family.  Been working on my own bikes for nearly 50 years…

Damn, the old learn something new every day can sure apply at times…

JIS on a t-handle is a weapon!

I have some genuine Kowa T-handles that were part of Honda's tool requirements back in the day. They really do work well.

I also was told that metric bikes had cheap screws and that's why they stripped out. Even clear back in the early 80's I heard that.

No wonder I can never find the right screwdriver that fits!

55 and just learned something new.

I found it last year, at 56.

Learned about JIS 8 years ago and boy did that save me a lot of stripped screws on carbs and my older Yamahas.....

I always just assumed that stripping carb screws was par for the course. I'd buy new ones every time I had to change jetting, because it was 50% or more likely that I'd mess up the screws when changing the jets. 

That was accurate for early Japanese bikes. Very soft material. My 83 KX125 was horrible even with hex heads and a socket.
