You may have over-oiled the filter. I would clean it again to remove the oil, and use half of what you used the first time.
It's easy to use too much oil, and it will make it run poorly.
I've done it...
Someone may have made "adjustments" to the carb as well, and replaced the OEM jets, and needles, with poor-quality aftermarket ones. Carb kits from Amazon are usually junk.
I always recommend OEM jets (not Dyno Jet either). Factory Pro jet kits use OEM Kehin jets. Sometimes rookies will drill out jets too, so you can't always go by what's in there now.
If you plan to go through the carbs, that would be my suggestion. Start from scratch. The stock jetting, even with a pipe and filter, is usually pretty good. Adding a shim under the needles will help smooth the midrange transition, but don't go with a stack of shims - just 1 is usually adequate.
