Edit; I'll let you know for definite on Thursday 😉

Lol, please do! If it is same then I am grabbing one.
I do see some slight differences in the pictures so guess you will first to find out.

Tried to figure out how to message Hazcat directly on this forum but couldn't figure that out. So hoping you see this...
I am curious to know how that carb has been?
Also if you had to fix or do any adjustments to the throttle for what Ski Pro said about it going from zero to hero in 1/8 of a crank?
I have a 1996 and the choke plunger broke off and I don't see a way to get the pieces out so the carb is shot. I saw that video Dual Dorks did and your post and thinking this Nibbi might be a nice alternative to get the bike going.

Works great, no problems. Here is the throttle I used and it has a 'standard' throw to it. Feels same as stock. The cable is too short and I had one made. Unfortunately I don't know what length it is, sorry. Here are the parts (toss the cable) It's all of $12 https://www.amazon.com/gp/product/B00ZI7SQR4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

The issue with throttle range, AKA 1/4 turn for example, is that the carb slide is so short, 28mm, and the throttles that I have found will turn 28mm in well under 1/4 turn. The one I found on Amazon was, at most, 1/8th of a turn. Now, I know of a way to modify the throttle tube on the bars: file out the groove the cable rides in so that the twist pulls less cable due to the smaller diameter. But it's not that easy to accomplish.
My hope is that someone discovers a throttle that works with this carb. I wouldn't have thought this was an issue going into this, but so far, I have not found a good throttle that works with this carb and allows for at least a 1/4 turn, preferably more, twist from DC to DayLight. (A term I learned in the military to describe the time or distance to travel from point A to B)

Have you considered using the factory cables and just rerouting the second one or tying it off out of the way? I was thinking about that.

That option is a strong possibility. Occam's razor, as it were....
I've yet to get on this though. Such a cool summer, highest temperature since October is 81 degrees! Getting my property in shape. When the hot weather hits, I'll move into the barn and work on the bike. In the meantime, my sunset view

My carb just showed up & yep, it's the exact same 28mm. Comes with 3 extra main jets (110, 112 & 118; 115 installed) & a pilot jet.

I need to mount it up & measure for a throttle cable. I'm tied up the rest of today, but once I do, I'll post the cable length. I'm hoping that one of the Nibbi cables will work without modification.

Awesome, I am interested to hear cable length and throttle cable solution, thanks!

I bought one of these Nibbi carbs for my XT200 and is supposed to arrive today. It currently has a single cable system which is stock to this bike so hopefully there I won't have to mod a cable that y'all do when putting it on the TW. I really hope the Nibbi works on the XT200 so I can use the choke/enricher which doesn't work on the XT200 OEM carb making it a b$t#h to start when it's cold.
Several years ago I bought a Clone of the original TW carb. TW riders have had varying degrees of success and failure with this carb. A couple of years ago I needed to clean or replace the pilot jet on Blue Bunny so I swapped in the clone to see how it worked. It's still in and the OEM carb is on the shelf with a new pilot jet. After some initial adjustments with the idle screw, it's been running as well as the OEM did when new. I did have to change the cable cam from the OEM carb to the Clone but other than that no other changes.

I posted a link to the throttle and guide I used. It's only $12. Cable is wrong length but at $12 for everything who cares that you still need the correct length cable.

I've got the NIBBI PE28mm carb on order from Amazon ($60) and the intake boot 5LB-14453-10-00 ($30) from Partzilla. I am going to hold off on throttle cable and see if I can run it, get a sense of the carb, with the stock cable (try to get the second cable out of the way).

The nipple on the carb end of the Nibbi is different, since it goes through the slide. Also the inner cable will need to be proportionately longer than the outer.
The original won't work.

ah shoot, probably missed that info in previous messages, otherwise everyone would probably just try that. Thanks for pointing that out to me!

Actually, it might work. The TW carb needs a fatter end. File it down to Nibbi size.
For length, with a Dremel, carefully cut and split the outside so the inner cable will work.

If you've got a blowtorch & access to solder, making cables is a cinch.

Believe this Nibbi throttle kit has the required 41" cable length without the 1/4 "quick" throttle but more of a standard throw.

I bought one, but it won't thread onto any motorcycle throttle I've ever found. I have several laying around from various 2-strokes, my currrent TW and the TTR parts bike I took the motor from.

I'm not above butchering one of the originals if it'll work. They'll be useless once the carb is switched anyway.

I bought one of those too. But what about your kill switch and starter button, built into the OEM throttle housing you'll have to yank to install this? I have a TTR spares bike, and the switches are separate from the throttle, so I might be able to make it work, But I have another problem with this kit: by the time the inner cable wraps though that throttle wheel and around the throttle and it's 1/4 turn twist, there's almost nothing left to thread down through the carb and attach to the slide and still have it close and open all the way. Looks like it would work on a Briggs and Stratton lawn mower type motor, but not a motorcycle slide carb without some mods. It MIGHT work if I shorten the outer jacket, but that's not an easy job. A Dremel tool and steady hand to peel enough back to expose more of the inner cable, but first to determine exactly how much within the adjustment range of cable's adjusters. (there are two: one at the throttle and one mid-way)

Would it work to use that cable with the original twistgrip?

My thoughts as well. I'm thinking the TTR225's throttle cable, heck even it's throttle housing, can be made to work.
My HOPE was a plug-n-play solution where my skills at carving up a generic cable and getting it all to work and not fail me 20 miles from the truck seems to be an unlikely dream these days...
BTW, the TTR's throttle assembly has a separate switch assembly for kill and the starter button. I don't know it's plug matches the TW's wire harness though. So keep in mind, anything you do with the throttle has the kill and starter switches built-in to the OEM throttle assembly. Simply thinking you can swap it out for a generic, like the one Fred linked, opens up that can of worms.
