Not sure exactly what you mean by thumb screw, there is a guy on flea bay that sells a small tool for carbs. It's actually for a larger v twin honda cruiser but it's the same D shape and it's about $6.
You can also try to contact Partsman here on the forum, he said he has some but I haven't seen him on here lately.

I think the problem is fitting your hands in there to turn the tool. Esp when it's hot. I think that's why most people seem to slot the screws and then use a Motion Pro Tool like this one.

Great if you have FCR carbs on your Superhawk, otherwise they won't work.
BTW, Motion Pro made the bits available to order separate finally for their 90 degree carb tool, for $3.15 ea. I think Tucker Rocky was the only one I could find that had them in their catalogs so I ordered 2 after snapping my Factory Pro tool on another bike with a seized d-shaped mixture screw. I ended up putting it in a socket that I used with a t-handle, but could use it with a small socket wrench and it's much thicker than the FP tool that they supply in their kits and sell separately....

I know I'm a few months late with this thread, but have recently been
reading a few posts concerning this subject.
Swazall has posted a link with the MotionPro D shaped tool. I deal
with motion pro, and can probably get my hands on one of these.
It's the X-mas vacation, and will not be in the office before a few weeks,
so will be looking into this in January. If indeed, I can get my hands on one, I will test, and report back if anyone interested.
Merry Christmas
Feliz Navidad

I bought a Motion Pro tool (had been led to believe it had the D-shaped tip, only to find it had a flat head screw tip). So, I picked up one of the small hand adjusters on eBay and, a bit of grinding and epoxying later, converted it to a D-tip. Now, back to the question at hand, you can get at the front carb but it takes practice and it's a bit tricky to know exactly when it's on properly. It's not a lost cause but it's not a walk in the park either.
I will be slotting the screws in the future and getting another MP tool. That won't ease the access but it will make it easier to see when it's on properly (with an extendible mirror). Some form of thumb screw certainly would be nice......

I bought a Motion Pro tool (had been led to believe it had the D-shaped tip, only to find it had a flat head screw tip).
It comes with various attachments including the D type for the US and other models that have stricter emissions controls.
As you can see the end is more shallow than the other type and has an open gear, I guess to save space and also I believe they are replaceable. Note the attachments are shorter than the norm also.
It's has also got a nice chunky, solid, and well built handle with markings on for counting your turns. This is kind of a clicky type movement via a grub screw in the side.
It steps/clicks in 1/6th increments. If you don't want the clicky steps, then the grub screw can be loosened off.
It's the best 90 degree screwdriver I have found so far, but still not perfect for the purpose in the case of the VTR. Accessing the carbs from the right hand side, the front fuel screw is easy, no problems at all. Though I am careful as to where I have the screw part on the carb rubber clips positioned.
The rear carb is another story. Yet again accessing the carbs from the right hand side, (the left is worse) I find the carb heater/water hose that cross's diagonally from the rear carb to front carb gets in my way, so I need to angle the screwdriver which does not help with getting the bit square on, so it slips off. Also the bottom of the screwdriver rests against the top of the the heater hose on the geared wheel, so this makes it more difficult to turn the handle. I can just about manage it, but it's tedious.
I think for you guys it will be even more tricky as you have the PLVR to contend with.
IMO thumbscrews are the way to go unless it's too hot to get in and turn them. Honda should have designed this better considering the importance of the fine tuning by ear/feel. Otherwise it's trial and error and a case of taking the carbs off and adjusting a bit at a time.

I would bet there are a few on this forum that would order that part if they can get it.

I'm suprised you guys are not already buying these instead of getting the dremel out. But even with these as mentioned previously, it's still a struggle to get in and adjust them.
And yes I believe the D type is designed to be tamper proof for stricter emissions controls.

That would be great, if you could get your fingers in there to adjust it. I just checked an extra OEM pilot screw that I've got in my tool box, and the taper tip on it is about twice as long as the tip on the knurled **** screw in the illustration.
But it is a great idea for a bike with more accessible carbs.

It would probably take a screw with tool-like apparatus attached that would enable access, but wouldn't vibrate out of position during operation. I'll make a couple tonite and let you try em out.haha

Try loggin in lazy. That's only for those non-members viewing and they certainly don't need to know about your knurled ****. I think you better slow down on the cocktails there sparky or you won't be able to put the gifts under the tree tonite.
Ouch!

I'm thinking there must be a way to attach a flexible extension of some kind to that damn screw. I bet the more fertile minds here on this forum will think of something. There HAS to be a better way to do this! BTW, I found this in my surfing tools, http://www.jetsrus.com/individual_parts/mp_08_0242.html
Wonder if it would fit?

go for it. If i had the mechanical know how, and if I had a brain, two big ifs i know ha, I'd do it myself. This could be a boon for anyone with contemptous carbs like ours. If it were merely a matter of stopping and adjusting the fuel screw in a minute or two, many more riders would learn that it is worth doing to keep their bikes running better and with better fuel economy. so, get her done!

yeah, that's the one for the tool pictured above in post 18 cybercarl. Now get $70 out and get you one.
That jets r us is a good link, but if you look on motion pro's site they also sell the bits individually, including the D adapter. You will also notice the Motion pro ones are about half the depth.
I like the flexible shaft idea. I'm sort of visualising something like a choke cable, but instead of a plunger, it has a mixture screw on the end. Then the other end could have a knulred **** like the idle adjuster. Imagine a couple of them mounted conveniently on the frame next to the choke or something.

It's all possible, they make them for FCRs
With the numerous extended mixture screws that currently exist, there must be one that would fit (which one, however, I have been unable to find any info about the one used on the VTR carb).....

the D socket is only a couple $ and the whole kit it probably $80+shipped.
the D socket on jetsrus is the motion pro brand, so are you saying that motion pro sells different length D sockets with diff parts #s? Strange.
