Uni filter and a pipe should be about 63-65 jet.

Although, foam and metal mesh filters get oil soaked and do not flow right after some time.

You could also run without an air filter if you arent riding on gravel roads or sand, then you'd need about a 67-68 jet.

If you're scared of running with no air filter, just cut the rubber elephant trunk off of the airbox mount, and take out the internal foam filter and grate out of the airbox, by removing the 3 screws to get inside. You dont need it, there is virtually zero chance of any dirt getting into your carb, as all the dust will get caught by all the internal surfaces coated in 2 stroke oil by the carb blowback...that is, if any dirt get in tge airbox in the first place, which is almost impossible.
