    1992 tw200 carb ?

    Can I use a post 2000 carb on a pre 2000 bike? If so are there any modifications needed? thanks

    Yes. You will need the manifold joint and the rubber air box boot from the 2001 and newer TW for a seamless fit.

    Try to get the old one working - in addition to the above (which are expensive from new) - you will find the cables leading in from the wrong side. The cable situation is an easy work around. The flat slider on the older models was superior in my opinion .....

    Got it running cleaned carb and tank, It will Idle with the choke pulled out but that is it. I am going to order a rebuild kit and try that. If I was to buy the new 2001+ carb is there any extra hoses or ports I would need to plug? Seems like I read that some where. thanks again

    the manifold boot I have seen on ebay and amazon are listed to fit 1987 to 2017 and appear to be the same as the one I have. And I see no air box boots any where un less you buy the whole box which looks to be the same

    There is no benefit at all by going from the old style carb to the newer style. Carbs is Carbs and one is no better or worse than the other. You said you have it cleaned but you do not say if you replaced the usual suspects inside of it so it will run right. The float valve and seat are the most common of issues IMO. Unless the jets are crudded up from nasty fuel corroding them there is usually not much reason to replace them. Check the enriching diaphragm to make sure the piston is moving freely and soak the stripped body in either Berrymans carb cleaner or run it through numerous cycles in an ultrasonic cleaner with some Pinesol. The boot from the air box to the carb is another of the usual suspects because they shrink and get very hard so they no longer form a tight seal. Any air leakage there can and will cause problems. Just buy a new boot and make absolutely sure the seal is air tight. The real problem with swapping from the old to the new carb is the diameter of the carb intake and engine side are different so you must change the boots to fit the new carb and then reroute the throttle cables. Not worth the trouble or expense IMO. A 2000 TW against a 2001 TW with their respective different carbs both correctly tuned do not run any better than each other so you get nothing by going to the newer carb.
