will an FCR carb off an Ex work on 450R

[gabelmatt]

Does anyone know if the fcr 39mm carb off an 400ex work on the new 450r without changing anything????

No that carb will not fit the bell sizes are different. You also would be missing the choke, tps, and hot start. I will have the FCR mx carb for the 450r in a few weeks they are just waiting for the new bells to be machined.:)
