90 degree screwdriver

[ddaniels]

What are you folks using to adjust the air mixture screws? My FZ1 is extremely tight in there. I found this one:

But it's pretty expensive.

I had need for such (those dern screws behind the cam end caps on 650G). I found the 0degree screw drives available were either too long or too short. So, with an ordinary propane torch and a vise and my own screw driver I bent one at the appropriate place for that application.

I take a 1/4" closed end wrench and hot melt glue a 1/4", short hex sided screwdriver bit into the closed end. It works particularly well if you have a 1/4" racheting wrench. If there is a bit more space, a 1/4" rachet with a 1/4" socket to hold a short driver bit also works.

If you buy a screwdriver at harbor freight, there is no need to heat it to bend it. NO, I'm not being facetious or snarky about that. LOL I have bent many of them by accident. heh On the other hand, if you need to drill a hole around a corner, their drill bits also bend very well. LMAO

I have that Motion Pro adjustment tool. It is indeed expensive. It is also of very high quality. Very well made. I have another as well. (I'll go find it, and attach it here) it was a LOT cheaper, but doesn't work as well. The MotionPro one, I will suggest right out of the box, to slightly disassemble it, and lose the little "clicker" ball. Works a lot better. In my opinion, worth the money, if you have it. NOW, after checking my old orders. The good one I bought, isn't "Motion Pro", but you can see it's the same tool. The crappier one I bought, is Motion Pro. Likely several brands made in the same sweatshop in china, lol...

AND, you can get the better one for $60

I have that first one and can't get it to fit under carbs 3 and 4. Plus, I can't tell if it's engaging with the screw slot.

 

[ddaniels]

I can't use something where you have to swing it left to right. Not enough room. I'll probably get the "good" motion pro one. Heck the picture in there add shows them using it on an FZ1.

 

[Sandy]

I don't know how much room you have under there, probably not much. What it use on the VM carbs is a screwdriver bit stuck in a 1/4" drive socket and wrap the large end of the socket with a layer of duct tape for some grip and also put a couple lines on it with a pen so I can easily tell how much I'm turning it. I can just manage to get it in there turn it with my fingers. I bet I've got a lot more room than you have though.

Definitely not enough room for my hands. I tried that. There are a bunch of bad reviews for that blue motion pro tool. I guess I'll keep looking.

 

[Spyder]

I haven't read the reviews, but in my experience with it, It was barely usable, until I took the "click" out of it. (which was really easy) It's just a tiny spring loaded BB inside the handle.

Once I did that, works great.

Yeah, that one was a disappointment right out of the packaging. On my old GS, I have a couple different screwdrivers about 2" long. I just reach my hand in there and adjust. But the GSXR won't have it. That cheap tool didn't come close to fitting in there. Plus it's like a cable drive inside that tube, and flexes. Hard to be accurate at all with it. Just sux. The blue one is the good one. I haven't found one that looks like it would work better than that one.

 

[ddaniels]

Well ok I guess I'll give it a try. Thanks.

 

[Rob S.]

Would this work? It ratchets.

 

[bwringer]

I have the Motion Pro tool.

It is indeed very nice quality and it is indeed kind of expensive.


So far, it's also been completely useless. There is simply no way to tell whether it's engaged with the screw. Plus there's just not enough space to get the tool in place on many bikes.


One of my more disappointing purchases, TBH.


That said, I've never worked on a Fizzy, so who knows; this tool or something like it might be the absolute cat's patoot for that job on that bike.

Nope. Not enough room to swing side to side. I need something that twists like a screwdriver.

Which one do you have, the one with gears or the cable driven one?

 

[Gorminrider]

...I've got a"90 deg" thing for $30 at the hardware store that is actually gear-driven and no slop...but mine is bulky and I filed it down before it would fit in amongst the obstructions...and I only have real success on one twin with it. There never seems to be room for it to sit up straight, even varying the screw bit length.

BUT on two other bikes, just a screwbit in a piece of heavy rubber brake hose.no "90 degree" stuff .. What's wanted is just something you can get up in there and turn with your fingers while you hold it tight to the screw with one contorted hand...luckily most pilot screws are fairly easy to turn.

....It's something to try .......maybe a little hose clamp can help hold the bit tight if your hose doesn't ...or, as an idea, a nut,washer or wingnut drilled out to suit the bits ....(adjusting the diameter of the "holder" adjusts your torque and accuracy turning the screw but ..too big and it can't be handled).

oh, put a tiny screw into the rubber hose to orient the tip so you have a clue where you're at per turns and where the slot end is oriented...

 

[ddaniels]

No room for my hands.

 

[Guest]

those wacky japanese and their contortionist mechanics at it again

 

[Spyder]

I commonly use one of those "free" pocket screwdrivers for my '83 GS. You know, the little ones with the pocket clip, and the (usually) magnet at the other end? I cut the plastic handle down, and hammer the shaft further into the handle. Ground a small line into opposite sides of the handle, and filled them in with a sharpie for half turn reference marks. Doesn't work On my GSXR though. Have to use the gear driven tool in question.
