I guess it's possible, but it just doesn't feel that way. When the bike is cold, I can rev it for several minutes w/o hesitation. Only once the misfiring begins, do I start smelling unburned fuel. The misfiring seems too abrupt to be fuel starvation and the backfiring can literally be felt through the seat.
Hopefully I'll find out when I take it in on Tuesday. I'm making note of all these suggestions to discuss with the mechanic.
