Bike stalls when holding clutch in and decelerating
 

The subject says it all, when I fully engage the clutch and decelerate rapidly coming up to a light my bike has been stalling for some reason. Anyone have this problem or know what probably wore out? The RPMs just keep dropping past idle, stop at 300 for a second, then go to 0, and at idle its at about 1200 RPM. Do I need to increase the idle RPMs or look at the clutch? Thanks!!

make sure all of the sensors are plugged in.
check for vacuum leaks.
check charging voltage and that the battery connections are clean and tight.

clutch is probably ok.
