I have a 08 700 switchback that bogs sometimes when it pulls through mid range. It may pull 6300 rpms and if I pump the throttle a few times it comes through it. I have two identical sleds with the exact same problem. Exhaust valves are all clean and primary is good. Checked rollers,weights and bushings and all are good.

How does the plugs look and the compression. Have you cleaned the carbs really well?
