Bike stalled today, has done it a few times. It happens in traffic at idle. The bike has had a popping sound I believe is from the carbs as soon as you bring the rpms up a touch. Bike restarts and when on the throttle or just cruising runs flawlessly. Im pulling it apart this weekend. Any ideas? Im just getting familiar with the bike. Im thinking dirty carbs, maybe a cracked boot, carbs out of sync? Any help is appreciated
 
Check your voltage while idling. You may have the dreaded low-voltage CDI issue. The CDI box needs good voltage to operate properly, and if acting up, will usually appear at rpms less than 2000, and normally will first occur after reaching operating temps AFTER the fan has kicked on.
