Under load?  Under WOT?  How about when the bike is not yet fully warm?  What about with the choke on slightly?  Do you have a pipe?  Are you using the stock airbox?  Have you changed the jetting?  Need more details.

Is it running on both cylinders? My bike would run to 6K but not over it on one cylinder. Is it "slow" as hell? Carb rebuild, would be my next step.

I would definitely point to the carbs. I think you will find crud in your main circuit. Could be sticking slide, or leaking CV boot too. Anyway the point is it's time for a cleaning.

Try pulling the plug wires while it's running one at a time if you pull one and leave the other on and it dies you're only running on one cyl.

+1. This will also tell you which carb to concentrate on... b/c yours are dirty.
