My k7 gsxr 750 has been having problems for a week or so now, ever since I got my valves adjusted. When I'm out riding, and then slow down (usually happens in anything over 3rd gear), when the revs get down to about 4000 or if i just ride around 4000 rpms, the bike's engine will just die. Then I can just drop the clutch and it starts back up, but it's really annoying and it just did it 4 times in a matter of 5 minutes. Also, i was having problems with the FI light coming on when it would die, but it hasn't done that for a few days now. Any ideas?
