That cr250 carb is going to be too big. I believe the cr250's have a 38mm carb on them.
There was a member on here selling a 35mm airstyker for around $150.

ya its a 38 keihin

 

[blasterracer817]

yea that cabs sold, it might not be tho i have an arisol kit soo it needs gas
BAD lol i have quit a few mods that are coming too

One thing to keep in mind is that the bigger the carb you put on it the less bottom end you'll have. A 38mm will work for drag racing but isn't a good choice for mx racing

well i found out the 125 has a 36 mm so ill check the 85c carb

Yeah the 38mm is wayy to much. Even with them mods you listed a 34mm carb will handle them just perfect,just jet the main,pilot and the needle jet right and you are good. Same with the airscrew.
