not a ttr250 but i just fixed a mates ttr 230 ordered a Chinese copy of the Yamaha carb the Chinese one was an exact copy, i used the jets and the bowl off the Chinese one to fix the original one. i didn't trust using the whole Chinese one. (a good fix for $70.)
I haven't looked at the 250 one though, so can't give any feedback.
Thanks for the suggestion. My 250 came with a Chinese copy carb and it’s been inconsistent, poor idle and throttle response. I’m trying to track down a genuine OEM or a Mikuni that’s been confirmed to fit and perform properly on the TTR250.
