I am a firm believer that when you get those kind of feelings, it is best to stay off the machine. You have the "Gift of Fear" and have recognized it. Sometimes if I am out on the bike and I know that I am not 100% in my confidence and skill, I go put it up! You have to be 100% while riding..not 90% or 95%, I am talking full blown 100%! Just like defending yourself from a BG, let your guard down just briefly and you could die!
If you decide to get back on, even after a couple of years, enroll in a Motorcycle Rider Course and get not only your "biker legs" back, but get back that defensive instinct and judgement skill needed to ride on the street.
