Well I took your advice and went for it. Boy is it a tight fit but boy does it run like it should now. THANK YOU. Two things I did that may help people. 1. I left off the return throttle cable. Works way better. 2. I used a heat gun to make soft the carb to air-box boot. It really runs like you would expect it to. This is a great upgrade but take some fanagling to make things work.
The old carb on my wife's 1998 TW bogged bad off idle as well. I tried cleaning the jets to no avail. I tried every possible setting of the air screw. I ordered and installed an "All Balls" carb rebuild kit, no improvement. I tried every possible setting of the idle screw on with the All Balls kit too. I tired adjusting the float. I must have had the carb in and out a half dozen times, to no avail. There is a diaphragm on the side of the carb that does not come in the All Balls kit so I didn't mess with that and was unable to find a replacement. So based on this video I went ahead and ordered a 2000-2017 carb on Amazon (Radracing was out of stock, but it's probably the same one). Total cost $60 Canadian which is about what the All Balls kit was. The problems: The choke on the new carb is extremely stiff. It takes a mighty pull to get it to come out. Disassembling it did not lead to any conclusions, the plastic retainer is just extremely stiff. The carb turned out to be a bit shorter than the stock one and I could not get the boots on properly, although they are on. I worried there was potential for a vacuum leak. I had the same problems with the throttle cables as discussed in the video. But who opens the throttle all the way with the steering all the way to one side and then lets go of the throttle under normal ridding scenarios? No one. I do not recommend letting go of the throttle while riding. So I thought if I had come this far, I may as well put the tank on and see what happens. It runs perfectly now. Thanks! Seriously folks, since the new 2000-2017 carb is virtually the same price as a rebuild kit, just get the new one. I don't know why new 1987-1999 carbs are not available but I couldn't find one. Perhaps because the 2000 can be made to fit and is a better carb? California emissions maybe? Ethanol? I'm not sure. Anyway my wife is very happy with the new carb, even though I am not sure she knows what it does or why the old one couldn't be made to work. Actually I'm not sure why the old one couldn't be made to work either, but the bike is fixed so long as the carb doesn't pop out of the boots.
I replaced the boots with the later model Yamaha boots. Intake boot and airbox boot. (they are actually different sizes then the older boots) Then it all fit perfectly.
I've had problems with my 87 that I just bought about 4 weeks ago. I've cleaned the carb twice and the bike runs great but every now and then it will just cut out. I read a lot of comments on the forums and it sounds like it isn't the carb. Everyone that I have talked to has said it's the CDI box. I ordered one so let's hope that it fixes the issue. If the bike idles and runs then obviously it's getting fuel and air. I don't think these old carbs are as bad as everyone says they are. Mine is set at 1 1/2 turns out and when it's running, it runs great and has great response. Just a thought before you change the carb on your TW. PS the CDI boxes are not cheap. :)
where would i find a rubber inlet and outlet boots? mine won't fit, and in inlet from the air cleaner is hard a rock. is there a specific size i need for this carburetor? Thanks.
Hi, have you got any advice how to find or adapt a carburator for my yamaha tw 125 2001 model? My one has an electric choke and is impossible to find and also one with manual choke looks like is not easy to find. My mechanic tried to adapt few carburators but they didn't work.
Worked great, but I am having a hard time getting the Throttle cables to be the right length. I tried bending the tabs, but still not getting things aligned and working smooth. Any suggestions are appreciated. Mine is a 97.
Hey! I purchased this same exact carb for my 89 tdub. I ran in to two issues: 1. It doesn’t fit on the air boot since this carbs diameter is bigger than the stock. 2. The end to end length of the carb is ~a quarter inch smaller than stock. I tried rotating the air boot to make it work but still unsuccessful. Any advice on these two would be greatly appreciated.
I just got one of these engines an its pull start do you have any idea what it is i have the serial number if needed. its got a broken shift shaft but i got another one with it an the fork. any help would be greatly appreciated.
Hi, I would like to do the same assembly on my TW 200 89, do not change the intake pipe and that of the air filter? it doesn't seem to be the same diameter.
@@JohnVHLife hi, any advice or link on what to fit on a yamaha tw 125 2001 model? Is the carb with the electric choke and so far there has been not 1 mechanic able to replace my carburator. With the carburators they tried the engine just jumms out.. I looking online and I can't really find anything. Thanks
Do not throw the old carb out all you would have had to do was clean the carb and blow the jets out and it would have ran like a champ but i get it new just feels great
Hi. I'm in similar situation but with a 1987 Suzuki DR200 has Mikuni 42A21 pumper flat slide carb that's missing parts. I saw these online very cheap (the CV style carbs) that say they will work but was afraid to even waste the $50 on a carb that would not work. I just trail ride, no racing or road riding. I hope that I can swap to the CV style?? If you have any suggestions, please let me know.
@@JohnVHLife last question I promise. Did you notice that the wider side of the carburetor was wider than the boot and really had to be coaxed into place? Feel like I got to put a little oil on the edge to get it in.
@@tortelvis1 Trying to remember, I watched the vid again and I didnt say anything about it, so I dont remember, if it was too hard I think I would have mentioned it in the video, so not sure exactly now, sorry.
I'm unable to find Radracing brand. Do u think the other carbs that fit 2001-2017 tw200 and TK250 are the same? I have a 1999 tw200 and not see any aftermarket carbs for it. A new carb for a 1999 is over $300 so I think I want to convert mine like u did.. thanks.
Click on my link. Then on that page they have similar items a little bit down. I see another one there. I’ll try to adjust my link to it when I get on a computer.
Anyone else who put this carb in find that the choke/fuel enricher plunger does absolutely nothing? Like, on a cold start if I pull the plunger fully out, absolutely no change in engine RPM... Everything else with this carb was pretty much plug and play, bike runs fine otherwise.

i wasted time doing the same kit and adjustments ,lol. 1990. i am ordering a China Carb.
I've got a 87 tw200 been sitting for a couple of years, needs a carburetor so thanks for the video it's helpful.
Glad it helped! Thanks for the comment!

Replacement of cdi with generic unit on eBay works fantastic
Thanks John. Hey, your bike is super clean for an 89!
Thanks!
I've got an 87 tw I'm currently restoring. It seems like everyone who owns any older tw has been letting it sit for a long long long time
where would i find a rubber inlet and outlet boots? mine won't fit, and in inlet from the air cleaner is hard a rock. is there a specific size i need for this carburetor? Thanks.
Update: I installed a Amazon $26 carb, it's running great.
I’ve got a 93 TW and am wanting to put this TW carb for the newer bikes on mine. Don’t you also need a newer rubber boot for the carb ?
Nope. Fits right up

Great video,thx.
Thanks for the great video will this work on a 1987
I think all the TW's are the same.
@@JohnVHLifeok thanks
Worked great, but I am having a hard time getting the Throttle cables to be the right length. I tried bending the tabs, but still not getting things aligned and working smooth. Any suggestions are appreciated. Mine is a 97.
I had to route mine differently to make it work, and its been working for years now, is it different than mine?
@@JohnVHLife Seems that the return cable is binding a bit (looks a bit old/rusty) so I just left it disconnected.
Hi thanks for the video, just wondering if you had to change the intake boot to fit the new carb?
Nope. Used the same one

Not sure what to say. Mine fit good. Length and diameter may be a little different. But it worked fine. My bike is an 89
You have to have the 2001 and up air boot if you're going to use that carburetor
I just got one of these engines an its pull start do you have any idea what it is i have the serial number if needed. its got a broken shift shaft but i got another one with it an the fork. any help would be greatly appreciated.
Have to google that one, sorry.
Hi,
I would like to do the same assembly on my TW 200 89, do not change the intake pipe and that of the air filter?

It fits in place of the factory carb, do not have to change anything.

Hello Sir, Is it a genuine carburetor? And is it good? I plan to install on my 150cc. Thank you !
Nope, follow the link and check it out, it works great though. I rode the bike yesterday, runs perfect!
The carbs are different, ordered one so it just as simple as hooking up the gas? No other adjustments? Than the ones on the video?
Watch the whole video. Had to fiddle with the throttle cables.
Do tou think that a new carburetor from 2021 can fit in ny 1997 tw?
yes

@@JohnVHLife I figured it all out...waiting on size 25 pilot jet to arrive in mail
@@dgmenace73 Oh? keep me posted!
Great video thanks! Hey is the only thing that holds that carb in place are those two rubber boots with the clamps? That's it?
Yep!
@@JohnVHLife any reasons why I couldn't use some new hose clamps instead of the old clamp brackets?
@@tortelvis1 Nope, should work fine I would think

Good question.
Thanks buddy

Thats pretty easy, and I explain how its done...
