I just got my jato today, and it looks awesome. I started it up and it runs fine, but it won't go at all until i get up to about half throttle. And even then it barely goes. I think the problem is the clutch. I loosed the slipper clutch all the way and it didn't do anything, nothing was turning on the slipper clutch. I took the motor out and pulled the clutch bell off to see if i could see anything. It all lookednormal, but the shoes were kind of hard to pull away from the center pin. There is a spring running all the way around both clutch shoes. I really don't know much about these clutches. When it got moving and i let off the throttle, i could hear something rubbing, it sounded like it was the clutch bell.
thanks guys
Joe
