I bought a 84' VF500 about two months ago. I've had it out a couple times and it's ran great. It was always a little rough when it was cold, but once it warmed up she ran and drove like a champ. I went to get on it yesterday and it started right up. It ran for about 2 minutes and then all the sudden the RPMs dropped down slowly and it died. I tried a bunch of times to get it started but couldn't. I let it sit for about 15 minutes and I was able to get it started again, although if the RPMs went under 2,000 it would die. My last ride was Saturday and she rode like a dream... It has been sitting ever since and no one has touched it. What gives?
