I followed the service manual instructions and I seemed to have the belt dialed in to about 34mm deflection at 10lbs. The belt was OK on the pulley, so I did not touch the left side adjuster nut. I retorqued the axle nut and got everything back on. On a test ride after about two tenths of a mile I was pulling out onto a street and gave it some power. I felt something slipping and there was reduced power. As soon as I could I pulled over and checked the belt as it felt that was where the problem was. The belt was sloppy loose, way worse than before I attempted to adjust it. It could easily be deflected all the way up. Any ideas what I did wrong and how to remedy? If i need to take it to the dealer, is it dangerous to ride with belt so loose?
