My money is on the carbs. Sounds like you are hitting the flat spot.

I don't think so. When the reg/rec goes south, it usually cooks the battery. That makes the bike stop running altogether. The 5-6K flat spot is well documented on these bikes. Take a look at the carb guide sticky posts at the top of the V4 workshop section... viewforum.php?f=24
