Installed backrest and belt tensioner and they work great, also new yoko back tire, with lamonts wheel balancer, front sprocket, and # 4 position linkage. What a differance. Cricket set at 160-180lbs. No vibration at 62-75 at all! The inside of the sprocket teeth were very sharp at 12k. Was not a hard chore. Small 3 jaw puller is a must. Used 648, comes out like molassas and sticks good, and we will see in 12k more miles. If will take heat to remove it though. Plenty room back of sprocket for a asbestos blanket to shield seal. Waiting for 7jurock windshield, till then, just enjoy. Tim
