Ok, long story short, I believe I may have just blown a motor. I was doing about 50mph and downshifted twice from 5th to 3rd as you usually do to pass a car, but as it turns out I was in 4th and downshifted into 2nd. Loud noises, super high rpms and now the motor is running on 1 cylinder. Give it to me straight boys, how bad did I just screw up? To make things worse, it is my wife's bike.
