Will not rev from idle after tuning

The bike ran just ok so I figured I'd check the timing and sync the carbs. The timing was good but when I adjusted the carbs the bike began to fail to rev. It idles great.

Note: Cylinders 1 and 2 smoke lightly and cylinder one backfires and does not heat as quickly when warming up from cold

Any help would be greatly appreciated
Thanks
