Check you're jetting. Check that you're actually getting 6psi to the actual carb. get one of those cheapo guages.
When is it leaning out? Top end? Idle? Bottom end? How are you sure it's actually leaning out and not flooding?
And a 650 IS WAY TOO BIG for a stock 12a. I have a 600, and I have a Street ported 13b think about it for a second....
650+12A=Bridge port. That's the only equation that makes sense.
Are you running the stock ports? A little more info would be extremely helpful
