I've been having all sorts of problems with my 2 stroke. Now that I've got it running after 2 weeks of repair, It won't go. It will start and idle great. I can rev it when it's idling. When I release the clutch my bike won't move. I lifted the rear tire and released the clutch. It will spin very slowly for about 3 seconds and then die. If I throttle it with the clutch out it will immediately die. I can not figure this one out? I want to go for a long ride soon I only have 25miles on it.
