Theres a breather from the right carb (the vacuum carb) going backwards and ends in a little filter. Make sure the filter sits higher than the airbox.
I've never had problems like that on my xt.
Perhaps you should also clean (use wd40 or special electric cleaner and a toothbrush) and grease (dielectric grease) all the connecters and plugs around the entire bike.
