If you decide you want a yz80 carb I have one in the garage that will work.

I bought it for my wifes TTR last year, but she got preggo and we sold the bike before I put it on.

I don't think it takes much to install, bolts right up. I think I was told that you could grind a little on the intake manifold to make it fit real well, but not necessary.

$50.00 including throttle.

ok im not going to argue with you guys. but i have never seen it done. just look at the 80 carb though compared to the ttr carb. on the 80 carb 1 intake end is twice as big as the output end. i dont see how you would make it fit onto the tiny ttr ariboot wich both ends on the ttr are of equal size

Well then I wouldnt want to take my bike to you because your wrong.We(me and PRC) put a 1997 yz80 carb on my bike.Ir ran awesome.If I remember correctly we put a 170 main/35 piolt jet and it ran awesome.Also the carb just slips right into the stock intake boot with no mods.

The YZ80 carb has a airbleed needle jet that makes it work once jetted very well on a TTR 125 and its various combinations

i have a spare '82 yz 125 carb im going to retro fit to the ttr carb. it will slip into the intake boot and there is room for it to fit. maybe this will really make the ttr rip

YZ carb mod

The last generation of round slide carbs from the YZ80 make great improvements to the TTR for little $$$ and fit right up with no modification. (2.5mm can be milled off the engine side for a perfect fit, but is not necessary.) They are particular about jetting, but make very good power. Look on Ebay and in junk yards for a clean model from 1982 to 2001. They are all basically the same and can be had for as little as $20. Strait from a YZ, they will be very rich on top and bottom, and lean in the middle on the TTR. A good place to start with rejetting is a 20-22.5 pilot and 140-150 main. The best needle is still undecided, but any of the richest Mikuni 4 or 5 series needles could work. (The stock YZ needle seems to fall just on the rich side of the middle of the charts in the Mikuni catalouges.) Slide sizes could also be changed. The YZ's slide is a #3. A #2 or even #1.5 could work well? Many folks have opt'ed to replace the stock O-0 needle jet with a P-4 size and keep the YZ needle. This seems to work well too. But remember, jetting will be different on nearly everyone's bike, so what works great for one, may not work as well for another. These are all just generalized places to start. Getting your bike finely tuned is half the fun. But overall, the YZ80 carb mod is very much worthwhile for the added power and response. It also enables the use of a pod filter, which is impossible with the stock carb. All necessary jet's and needles can be found here: http://www.sudco.com/ and here: http://www.mikunioz.com/
