So most likely there's something non-stock inside carbs themselves. Non-stock jet sizes, perhaps even non-stock needles and/or heights. This is most likely issue since most common issues are in opposite direction with clogged jets & circuits causing lean mixtures.
Don't assume printed number on jets is actually what's being used. You'll want to measure jet-sizes by inserting soft-copper wire of increasing size until you find one that's snug. Then measure wire with micrometer/calipers.

Ok will do. If I can get it close with the mixture screws we will at least be able to ride for a bit longer. Once it gets a little more chilly I will tear them down again for a full inspection.
Would a "stock jet kit" be the way to go if they are indeed oversized?
Again, I cannot stress enough how thankful I am to you all for all of your patience, understanding, and support.
