Default 250x jetting question

Hello all, just picked up a 250x w/ carb issues... Rather than rebuilding I picked up a 300ex carb. the only mods to the 250x are K&N filter and Cobra exhaust. Everything I read tells me the stock 300ex will be good. However the main jet on a 250x 125 and the stock 300ex is a 122. The pilot jet is larger in the 300ex. Will I be able to bolt and go?

Thanks.

Chris
