I have never found the 250 single to be very jet sensitive. once you have a good setup and it is not blubbering and exhaust temps are not to high leave it alone. Unlike a 125 you do not have to be right on the verge of detonation for it to be fast. I run the same jet almost all the time unless there is extreme air changes or you go to Miller in Utah.
